    [00026] Systems and devices for the control and monitoring of liquid applications in agricultural fields are described in this document. In one embodiment, an implement includes several row units with flow devices (eg control and monitoring units) for liquid applications. A control and monitoring pump controls a flow of liquid from a storage tank to each of the flow devices. In one example, a control and monitoring unit (CMU) includes a valve (eg, a ball valve, an offset ball valve) having an opening to control the flow of a liquid through the valve to an outlet. A first passage of the CMU provides a first flow path having a first flow rate from an inlet to the valve. The first pass includes a first flow meter to monitor the flow of liquid through the first pass. A second CMU passage provides a second flow path having a second flow rate from the inlet to the valve. The second passage includes a second flow meter to monitor the flow of liquid through the second passage.
    [00027] The control and monitoring pump can control all implement CMUs or a group of CMUs. The control and monitoring pump and CMUs have a wide operating range of flow rates (eg up to 60x) in contrast to conventional flow devices and pumps. Each of the CMUs can include two passes having different operating ranges of flow rates in order to provide a linear response to sensed flow rates across an entire operating range of flow rates.
    [00028] In the description that follows, numerous details are defined. It will become apparent, however, to a person of skill in technology, that the modalities of the present description can be practiced without these specific details. In some cases, well-known devices and structures are shown in the form of a block diagram, rather than being shown in detail, in order to avoid obscuring the present description.
    [00029] Fig. 1 shows an example of a system to perform agricultural operations in agricultural fields that includes the operations of an implement according to a modality. For example, and in one embodiment, system 100 can be implemented as a cloud-based system with servers, data processing devices, computers, etc. Aspects, features, and functionalities of system 100 can be implemented on servers, seeders, seeder monitors, combinations, laptops, tablets, computer terminals, client devices, user devices, handhelds, personal digital assistants, cell phones, cameras, smart phones, mobile phones, computing devices, or a combination of any of these or other data processing devices.
    [00030] In another embodiment, the system includes a computer network or a processing device embedded within another device (eg a display device) or within a machine (eg a seeder, a combine) or other types of data processing systems having fewer components or perhaps more components than those shown in Fig. 1.
    [00031] System 100 (eg a cloud-based system) and agricultural operations can control and monitor liquid applications with the use of an implement or machine. The system without includes machines 140, 142, 144, 146, and implements 141, 143, 145, coupled to a respective machine. Implements (or machines) may include flow devices to control and monitor liquid applications (eg a sprayer, a fertilizer) of crops and soil within associated fields (eg fields 102, 105, 107 , 109). The system 100 includes an agricultural analysis system 102 which includes a weather store 150 with historical and current weather data, a weather forecast module 152 with the weather forecasts for the different regions, and at least one system of processing 132 to execute instructions for controlling and monitoring different operations (eg liquid applications). Storage medium 136 may store instructions, software, software programs, etc., for execution by a processing system and for carrying out the operations of agricultural analysis system 102. An image database 160 stores captured images of the crops at different stages of growth. A data analysis module 130 can perform analysis on agricultural data (eg, images, weather, weather, yield, etc.) to generate crop forecasts 162 related to agricultural operations.
    [00032] A field information database 134 stores agricultural data (eg crop growth stage, soil types, soil characteristics, moisture holding capacity, etc.) for the fields being monitored by system 100. An agricultural practices information database 135 stores farm practices information (eg, planting as applied information, spray as applied information, fertilization as applied information, planting population, applied nutrients (by eg nitrogen), yield levels, owner indices (eg seed population rate for a soil parameter, etc.) for the fields being monitored by system 100. An implement can obtain application data from from the CMUs and provide this data to the system 100. A price/cost database 138 stores input cost information (eg seed cost, cus nutrient (eg nitrogen)) and commodity price information (eg harvest revenue).
    [00033] The system 100 shown in Fig. 1 may include a network interface 118 for communicating with other systems or devices such as drone devices, user devices, and machines (e.g. seeders, combined) by means of a 180 network (eg Internet, wide area network, WiMax, satellite, cellular, IP networks, etc.). The network interface includes one or more types of transmitters for communicating via network 180.
    [00034] Processing system 132 may include one or more microprocessors, processors, a system on a chip (integrated circuit) or one or more microcontrollers. The processing system includes logical processing for executing software instructions from one or more programs. System 100 includes a storage means 136 for storing data and programs to be executed by the processing system. The storage medium 136 can store, for example, software components such as software applications for the control and monitoring of liquid applications or any other software application. Storage medium 136 may be any known form of machine-readable non-transient storage medium such as semiconductor memory (e.g., Flash, SRAM, DRAM, etc.) or non-volatile memory such as hard disk or a solid state drive.
    [00035] While the storage medium (for example, a machine accessible non-transient medium) is shown in exemplary mode as being a unique medium the term "machine accessible non-transient medium" should be understood to include a unique or a multiple means (eg, a distributed or centralized database, and/or associated caches and servers) for storing one or more sets of instructions. The term "machine-accessible, non-transient medium" should also be understood to include any medium that is capable of storing, encoding, or transporting a set of instructions for execution by a machine and that causes the machine to perform either or more of the methodologies in this description. The term “machine-accessible non-transient medium” is also to be understood in this sense to include, but not be limited to, solid-state memory, magnetic and optical media, and transport wave signals.
    [00036] Fig. 2 illustrates an architecture of an implement 200 to control and monitor applications (eg liquid applications, fluid mixture applications) in one modality. Implement 200 includes at least one storage tank 250, flow lines 260 and 261, a flow controller 252 (e.g., a valve), and at least one variable rate pump 254 (e.g., electric, centrifugal, piston, etc.) to pump and control the application rate of a liquid (eg application of a liquid, slurry) from at least one storage tank to different control and monitoring units (CMUs) 220227 (eg , flow devices 220-227) of the line units 210-217, respectively of the implement. In one example, each line unit includes a CMU to control and monitor a liquid (eg, the flow rate of a liquid) applied to the soil or a crop in a field.
    [00037] In one example, variable rate pump 254 controls the pumping of a liquid from storage tank 250 to each of the CMUs. In another example, implement 200 includes several storage tanks. Pump 254 controls the pumping of a first liquid (eg the first type or fertilizer) from the storage tank 250 to each of the CMUs and controls the pumping of a second liquid (eg the second type or fertilizer) from an additional 250 storage tank for each of the CMUs.
    [00038] In another example, the implement 200 includes several control pumps. Each of the control pumps includes a section or group of line units. A first control pump can control CMUs 220-223 while a second control pump controls CMUs 224-227. The control pump can have a flow rate range of 0.5 to 30 gallons per minute (gpm) while a CMU can have a flow rate range of 0.05 to 3 gpm.
    [00039] In another example, a pump includes an external flow control and external sensors. Each CMU (eg, flow devices) includes line-by-line detection, monitoring, and mapping functionality. Liquid application data can be used to generate user interfaces that show a field map of liquid application. For example, a first region of a field may have an application of 100 units of nitrogen and a second region of a field has an application of 50 units of nitrogen. This data can be compared or overlaid with other data such as production data. Each CMU can also provide a line by line control functionality for swath control if desired to turn off liquid application by region(s), turn compensation by flow rate compensation during one implement turn, and variable rate for liquid application in such a way that each line unit can set its flow rate independently of other line units. The valve and two passages eliminate the flow device orifices (eg CMU).
    [00040] Fig. 3 illustrates a flow device (for example, a control and monitoring unit) to control and monitor applications in a field according to a modality. The flow device (eg a control and monitoring unit (CMU) 300) includes an inlet 302 for receiving a liquid (eg liquid application, slurry, fertilizer application, a chemical application) that flows in directions 304, 311, 321 and 334 to the entrance and then further into the first passage 310 and the second passage 320. The passage 310 is defined by a side wall 314 and a side wall 324. (eg a low flow passage) includes a 312 flowmeter (eg turbine style, Hall Effect turbine flowmeter, Turbo Flow® Series FT-110 turbine flowmeter available from Gems Sensors & Controls in Plainville , CT) which is designed to measure a flow rate through the flow meter. Passage 320 (eg a high flow passageway) also includes a flowmeter 322 (eg turbine style) that is designed to measure a flow rate through this flowmeter. Sidewalls 324 and 326 are coupled to a movable member 332 which is coupled to a spring 330 and to members 333 and 335. Ball valve 350 is positioned between members 354 and 355. The ball valve is rotatable or moved such that an opening 352 is positioned in an open position as illustrated in Fig. 3 to allow liquid flow or in a closed position (e.g., opening when rotating 90 degrees, open when vertically aligned).
    [00041] In an example of flow, a liquid (or fluid) enters through inlet 302 and then goes into passages 310 and 320. The liquid in passage 310 flows through flow meter 312 and then , flows through the opening 352 when the ball valve has its open position as illustrated in Fig. 3. The fluid then flows through the outlet 390 with a direction 358. The liquid that flows past passage 320 flows through from flowmeter 322 and then went to member 332 in direction 337. Spring 330 opens (eg compresses) when pressure on the first surface (eg, upper surface) of member 332 exceeds pressure on the second surface (eg, the lower surface) of member 332. Member 332 moves in a direction 338 when the spring is in its open position as illustrated in Fig. 4 according to one embodiment. Member 332 is supported by members 333 and 335 and by spring 330. The flowing liquid passes through member 332 in a direction 334 when spring 330 opens and member 332 is forced to an open position. The liquid then flows through opening 352 in a direction 358 towards outlet 390.
    [00042] Fig. 4 illustrates a spring 430 in an open position according to an embodiment. Member 432 (eg, member 332, member 532) moves downward causing spring 430 (eg, spring 330, spring 530) to compress. A liquid flows as indicated by arrows 437, 438 and 434. Member 432, if flexible, may move or shift non-uniformly or bend to create a flow path for the liquid.
    [00043] Fig. 5 illustrates a flow device (for example, a control and monitoring unit) to control and monitor applications in a field according to a modality. The flow device (eg the control and monitoring unit (CMU) 500) includes input 502 for receiving a liquid (eg a liquid application, a slurry, a fertilizer application, a chemical application) which flows in directions 504, 511, 521 and 534, into an inlet 502 and then additionally into a first passage 510 and into a second passage 520. The passage 510 (e.g., a passageway flow meter) is defined by a sidewall 514 and a sidewall 524. Passage 510 includes a flowmeter 512 (e.g., turbine style) that is designed to measure a flow rate through the flowmeter. Passage 520 (eg, a high flow passage) also includes a spring 522, members 570572, and a flowmeter 528 (eg, turbine style) that is designed to measure a flow rate through this flowmeter. Member 570 is coupled to sidewall 526 while member 572 is coupled to sidewall 524. A movable member 571 is coupled to spring 522. A ball valve 550 is positioned between members 554 and 555. The ball valve may be rotated or moved such that an opening 552 within the ball valve is positioned in an open position as illustrated in Fig. 5, in order to allow a flow of liquid, or in a closed position (e.g., open when rotating 90 degrees, open when vertically aligned).
    [00044] The flow meter 528 may be arranged to intercept all flows through the second passage 520. In other embodiments the flow meter 528 may be arranged to intercept only a portion of the flow (e.g., disposed offset from the passage walls 520, having an outer radius smaller than an outer radius of passage 520) such that a portion of the fluid is allowed to flow through flow meter 528 without passing through (and/or being measured) by flow meter 528. In such embodiments, the signal generated by flow meter 528 is preferably converted to an estimated actual flow value by reference to an empirical database.
    [00045] The relative size of the passages (eg 510, 512), the position and size of the flow meters (eg 512, 528) relative to the associated passages, and the flow rate and/or pressure required for flow through these passages (for example, the flow rate, pressure and/or flow required to override the force of spring 522) are preferably selected such that the minimum and maximum flow rate through each of these flowmeters (eg 512, 528) are within desired ranges which are preferably within accurate measurements (eg within .01%, .1%, 1%, 2% or 5%) of the flow rate for each. Put another way, for each total flow rate through the CMU 500, the split of the flow is preferably balanced (eg, proportionally split, shared) between the two passages such that the flow rate through the first flow meter 502 is within a first desired range (eg a precisely measured range) associated with the first flow meter and the flow rate through the second flow meter 528 is within a second desired range (eg a measured range precisely) associated with the second flowmeter.
    [00046] In an example of flow, a liquid enters through an inlet 502 and then flows into passages 510 and 520. The liquid, in passage 510, flows through the flow meter 512 and then flows through the opening 522 when the ball valve is in an open position as illustrated in Fig. 5. The liquid then flows through the outlet 590 with a direction 558. The liquid that flows into the passage 520 flows into the interior. of a member 571 which is coupled with spring 522 which opens (e.g. compresses) when pressure on a first side of member 571, which is opposite to the spring, exceeds pressure on a second side of member 571, which is adjacent to or in contact with spring 522. Member 571 moves in a direction 538 towards the spring (away from members 570 and 572) in order to cause the spring to compress in an open position. When the spring is in an open position, the flowing liquid passes through member 571 in a direction 538 and then through flowmeter 528. The liquid then flows in a direction 534 through opening 552 in a direction 158 toward output 590. Spring 522 provides functionality in holding a flow path through passage 520 closed until a flow rate has reached a certain range, such that measurements from flow meter 528 are accurate. .
    [00047] Fig. 6 illustrates a flow device (for example, a control and monitoring unit) to control and monitor applications in a field according to a modality. A flow device (eg, control and monitoring unit (CMU) 500) includes an inlet 602 for receiving a liquid (eg, a liquid application, a slurry, a fertilizer application, a chemical application ) which flows into inlet 602 and then additionally into a first passage 610 in a direction 611, and in a second passage 620 in a direction 621. The passage 610 (for example, a passage of high flow) is defined by a sidewall 614 and a sidewall 624. Passage 610 includes a flowmeter 628 (e.g., turbine style) that is designed to measure a flow rate through the flowmeter. Passage 620 (eg a low flow passageway) also includes a flowmeter 612 (eg turbine style) that is designed to measure a flow rate through this flowmeter. A ball valve 650 can be rotated or moved such that an opening 652 within the ball valve is positioned in an open position, as illustrated in Fig. 6, in order to allow liquid flow, or in a closed position. with the aim of not allowing the flow of liquid.
    [00048] In a flow example, a liquid enters an inlet 602 and then flows into passages 610 and 620. The liquid in passage 610 flows through flowmeter 628 and then flows through from a cross-sectional opening 640, into the opening 652, when the ball valve is in its open position, as illustrated in Fig. 6. The liquid then flows through an outlet 690 with a direction 692. Liquid flowing into passageway 620 flows through flowmeter 612. The liquid then flows through cross-sectional opening 642, into opening 652, in a direction 692 through outlet 690. cross-sectional openings 640 and 642, of region 641, are uniquely designed such that a low flow path through passage 620 slowly opens as ball valve 650 initially begins to rotate from a closed position. to a partially open position and, and Next, subsequently, a high flow path through passage 610 begins to open as the ball valve continues its rotation and additionally opens as illustrated in Fig. 6. In this example, the cross-sectional opening 642 of the low flow path has a smaller area compared to the cross-sectional opening 640 of the high flow path.
    [00049] Fig. 7 illustrates an exploded view 741 of a region 641 having cross-sectional openings between passages and a ball valve according to an embodiment. The cross-sectional openings 740 and 742 correspond to the cross-sectional openings 640 and 642, respectively, in Fig. 6. The dimensions of the cross-sectional openings 740 and 742 vary as the ball valve rotates or moves causing an increase. in the available cross-sectional area of an opening (eg, opening 652) through the ball valve.
    [00050] In one example, a ball valve rotates or moves from a closed position as shown with dashed line 750 to a partially open position (eg dashed lines 751-754) or fully open as shown with the dashed line 755. A low flow path through a passage (eg, passage 620) slowly opens as the ball valve 650 starts to rotate from a closed position of the dashed line 750 to a partially position. open of the dashed lines 751-752. It will be appreciated that the dashed lines of Fig. 7 represent an edge of the opening 652 where the opening is to the right of the dashed line. A high flow path is not flowing during these positions, as shown by dashed lines 750-752, not intersecting with opening 740. Subsequently, a high flow path through a passage (eg passage 610) begins to opens as the ball valve continues its rotation and opens further, as illustrated in Fig. 7 with dashed lines 753-755, intersecting with the cross-sectional opening 740. In this example, the cross-sectional opening 742 of the low flow path has a smaller area compared to the cross-sectional opening 740 of the high flow path.
    [00051] The opening 742 preferably has a gradually enlarged shape (eg generally triangular) and preferably generally thinner than an opening 740; thus a relatively wide range of ball valve movement corresponds to a gradual increase in the flow rate in the low flow range, in which flow is only allowed through the low flow passage. Aperture 740 is preferably generally wider than aperture 742 and preferably of a generally constant width (e.g., generally trapezoidal in shape); as a result, a relatively small range of ball valve movement is thus required to introduce a relatively high flow to the high flow passage, the result of which may be preferable in embodiments in which the flow meter 528 associated with the passage high flow, does not operate accurately or at all relatively at low flow rates.
    [00052] Fig. 8 illustrates an upward view (e.g. a side elevation view from the outlet end) of a flow device having a ball valve with multiple flow passages according to an embodiment. The flow device 800 (e.g., CMU) includes a ball valve 850 having an opening 852. A liquid or fluid flows through the opening 840 from a passage (e.g., a high flow passage) to the opening 852. Liquid also flows through the opening 842 from a passage (e.g., a low flow passage) into an opening 852. A member 824 (or side wall) divides the openings 840 and 842. The ball valve includes 854 and 855 support members. An 860 actuator rotates or moves the 850 ball valve for the purpose of adjusting the 852 port positions.
    [00053] Conventional flow devices or valves may have limited flow ranges and control issues. Fig. 9 illustrates a graph of a percentage of maximum flow versus a percentage of displacement for conventional valves. Graph 900 illustrates the non-linear flow performance of conventional devices such as the 910, 920, 930 and 940 valves. These valves have an operating range of approximately 10x in which an auto flow rate limit is approximately 10x greater than a low flow rate limit.
    [00054] Fig. 10 illustrates a graph of a flow rate versus operating regions for a flow device (eg CMU) having two flow paths according to a modality. The flow device (e.g., flow devices 220-227, 300, 500, 600, 800) includes two two-pass flow paths (e.g., 310, 320, 510, 520, 610, 620). A low flow passage has a 1010 flow of liquid in a region 1020 while a high flow passage does not have a 1012 flow of a liquid in region 1020. A ball valve (eg 350, 550, 650) transitions from from a closed position to a partially open position during region 1020. The ball valve transitions from a partially open position to a fully open position during region 1030. A high flow 1012 starts to flow a liquid at the beginning of the region 1030 while a low flux 1010 rises smoothly (if not all) during a first portion of region 1030 and then rises smoothly during the second portion of region 1030. By combining the low flux 1010 and the high flux 1012, a full 1014 flow has a linear response over an entire operating range that includes both the 1020 and 1030 regions. In one example a high flow limit is 60x greater than a low flow limit. The 1010 Low Flow provides an accurate flow measurement even at low flow rates and the 1020 High Flow provides a large flow capacity.
    [00055] For different flow ranges, different measurements from flow meters or flow estimates can be used. Fig. 11 illustrates a graph of flow rate versus operating regions for different operating regions of a flow device according to a modality. The flow device (eg 220-227, 300, 500, 600, 800 flow devices) includes two two-pass flow paths (eg 310, 320, 300, 510, 520, 610, 620) . A low flow passage has a detected flow 1110 of a liquid in a region 1120 while a high flow passage does not have a detected flow 1112 of a liquid in region 1120. A ball valve (eg 350, 550, 650) transitions from a closed position to a partially open position during region 1120. The ball valve transitions from a partially open position to an even more partially open position during region 1130. A low flow passage continues with flow detected increased 1110 while detected high flux 1112 also starts to flow a liquid at the beginning of region 1130. The detected high flux flow rate 1112 may be difficult to measure during region 1130, therefore, an estimate of the detected high flux rate can be used for this region 1130. The estimate of an opening area of a high flow passage to estimate the high flow rate is based on the known relative areas of the paths. s of high and low flow. A position sensor can be placed on the ball valve for the purpose of determining these relative areas of the high and low flow paths.
    [00056] In region 1140, low flow passage continues with increased detected flow 1110 and may saturate (for example, at a flow rate of 0.50) while high detected flow 1112 continues to increase at a flow rate of liquid. The high sensed flux rate can be reliably detected during region 1140. By combining the low sensed flux 1110 and the high sensed flux 1112, a total sensed flux 1114 has a linear response over an entire operating range and corresponds to one 1116 full flow which also has a linear response over an entire operating range. In one example, a flow meter for low sensed flow 1110 can accurately measure a flow between approximately 0 and 0.5 gallons per minute, and a flow meter for high sensed flow 1112 can accurately measure flow between 0 .25 and 2.5 gallons per minute. In another example, the flow meter for high sensed flow 1112 can accurately measure a flow between 0.75 and 2.5 gallons per minute.
    [00057] Fig. 12 shows an example of a system 1200 that includes a machine 1202 (eg a tractor, a combined harvester, etc.) and an implement 1240 (eg a seeder, a cultivator, a plow, a sprinkler, a spreader, an irrigation implement, etc.) according to a modality.

The 1215 network interface can be integrated with the 1210 machine network or separate from the 1210 machine network as shown in Fig. 12. The 1229 I/O ports (eg on board diagnostic/diagnostic (OBD) ports ) enable communication with another data processing system or devices (eg display devices, sensors, etc.).
    [00058] In an example, the machine performs operations of a tractor that is coupled to an implement for liquid applications in a field. The flow rate of applying a liquid to each row unit of the implement can be associated with the positioning data at the time of application to get a better understanding of the liquid applied for each row and region of a field. Data associated with liquid applications can be viewed with at least one of display devices 1225 and 1230.
    [00059] Processing system 1220 may include one or more microprocessors, processors, a system on a chip (integrated circuit), or one or more microcontrollers. The processing system includes processing logic 1226 for executing software instructions of one or more programs and a communication unit 1228 (e.g., a transmitter, a transceiver) for transmitting and receiving communications from the machine via the network. machine 1210, or network interface 1215, or implement via an implementation network 1250, or network interface 1260. Communication unit 1228 may be integrated with the processing system or separate from the processing system. In one embodiment, communication unit 1228 is in data communication with machine network 1210 and implement network 1250 via a diagnostic/OBD port of I/O ports 1229.

System 1200 includes memory 1205 for storing data and programs for execution (software 1206) via the processing system. Memory 1205 can store, for example, software components such as liquid application software for analyzing liquid applications for the purpose of carrying out the operations of the present description, or any other software module or application, images (by example, crop image captures), alerts, maps, etc. Memory 1205 can be any known form of a machine-readable, non-transient storage medium, such as a semiconductor memory (e.g., flash; SRAM; DRAM; etc.), or a non-volatile memory such as hard disks or a solid state drive. The system may also include an audio input and output subsystem (not shown) that may include a microphone and speaker to, for example, receive and send voice commands for user authentication or authorization (eg, biometrics ).
    [00061] Processing system 1220 communicates bidirectionally with memory 1205, machine network 1210, network interface 1215, header 1280, display device 1230, display device 1225, and input and output ports 1229, via communication links 1230-1236, respectively.
    [00062] Display devices 1225 and 1230 can provide visual user interfaces for an operator user. Display devices can include display controllers. In one embodiment, the display device 1225 is a portable tablet device or a touch sensitive touch screen computing device that displays data (e.g., liquid application data, captured images, localized visualization map layers, application data of liquids as applied from high definition field maps, crop or planting data or other agricultural parameters or variables, yield maps, alerts, etc.) and data generated by an agricultural data analysis software application, and inputs received from a user or operator for an exploded view of a region of a field, monitoring and controlling field operations. Operations can include setting up the machine or implement, reporting data, controlling the machine or implement including the sensors and controllers, and storing the generated data.

    [00063] A 1270 cab control module may include additional control module to enable or disable certain machine or implement components or devices. For example, if the user or operator is not able to control the machine or implement using one or more of the display devices, then the cab control module may include switches to turn off or close machine components or devices or implement.
    [00064] Implement 1240 (for example, a seeder, a cultivator, a plow, a sprinkler, a spreader, an irrigation implement, etc.) includes a network of implement 1250, a processing system 1262, a network interface 1260, and optional 1266 input and output ports, for communicating with other systems or devices including the 1202 machine. The 1250 implement network (eg, a serial bus protocol network controller (CAN) area network, an ISOBUS network, etc.) includes a 1256 pump for pumping a liquid from 1290 storage tank(s) to CMUs 1280, 1281, ...N of implement, 752 sensors (eg speed sensors , seed sensors to detect the passage of seeds, down force sensors, actuator valves, OEM sensors, flow sensors, etc.), 754 controllers (eg GPS receivers), and a 762 processing system for control and monitor machine operations. CMUs control and monitor the application of liquids to the crop or soil as applied by the implement. The application of liquids can be applied at any stage of crop development including within a planting trench over seed planting, adjacent to the planting trench in a separate trench, or in a region that is close to the planting region (by between two rows of corn or soybeans) having the seeds or crop growing.
    [00065] OEM sensors can be moisture sensors or flow sensors for a combination, speed sensors for the machine, seed force sensors for a seeder, liquid application sensors for the sprayer, vacuum, elevation, low sensors for an element. For example, controllers can include processors in communication with a plurality of seed sensors. Processors are configured to process the data (eg liquid application data, seed sensor data) and transmit the processed data to the 1262 or 1220 processing system. Controllers and sensors can be used to monitor the motors and drives in a seeder, including variable rate steering system to change crop populations. Controllers and sensors can also provide swath control to close individual rows or planter sessions. Sensors and controllers can detect changes in an electric motor that controls each row in a planter individually. These sensors and controllers can detect seed delivery speeds in a seed tube for each row of a planter.
    [00066] In one example, the sensors include ion selective and IR spectroscopic electrodes for measuring different nutrients (eg nitrogen, phosphorus, potassium, etc.) from the soil samples. A liquid application rate can be dynamically changed in-situ in a region of a field during an agricultural operation by controlling and monitoring the units and flow devices described in this document based on a quantity of soil nutrient measurements (by example, recently measured soil nutrients, real-time dynamic measurement amount of different nutrients) in the region of the field that is being measured during the agricultural operation or that has been previously measured for a particular region of the field. Sensors can also include optical, soil temperature, and soil conductivity sensors.

    [00068] Processing system 1262 communicates bidirectionally with implement network 1250, network interface 1260, and input and output ports 1266, via communication links 1241-1243, respectively.
    [00069] Implement communicates with machine via wired and possibly also via 1204 wireless bidirectional communication. Implement network 1250 can communicate directly with machine network 1210 or via network interfaces 1215 and 1260. implement can also be physically coupled to machine for agricultural operations (eg planting, harvesting, spraying, etc.).
    [00070] Memory 1205 may be a machine-accessible, non-transient medium in which is stored one or more sets of instructions (eg 1206 software) incorporating any one or more of the methodologies or functions described in this document. Software 1206 may also reside, completely or at least partially, within memory 1205 and/or within processing system 1220 during execution thereof by system 1200, the memory and processing system also being machine-accessible storage media. . Software 1206 may additionally be transmitted or received over a network via network interface 1215.

While the machine-accessible non-transient medium (eg, memory 1205) is shown in exemplary mode as being a single medium, the term “machine-accessible non-transient medium” should be taken to include a single medium or a multiple medium (eg, a distributed or centralized database, and/or servers and associated caches) that store one or more sets of instructions. The term "machine-accessible non-transient medium" should also be taken to include any medium that is capable of storing, encoding, and transporting a set of instructions to be executed by a machine and that cause the machine to carry out any one or more of the methodologies in this description. The term “machine-accessible non-transient medium” should, in this sense, be taken to include, but not be limited to, solid-state memories, magnetic and optical media, and wave signal carriers.
    [00072] Turning now to Figs. 13 and 14, an alternate flow device 1300 is illustrated in accordance with an embodiment. Flow device 1300 preferably includes a low-flow cavity 1310 (preferably in fluid communication with a low-flow fluid source), a high-flow passageway 1320 (preferably in fluid communication with a low-flow fluid source). high flow fluid having a higher operating pressure than the low pressure fluid source), and an outlet passage 1330 (preferably in fluid communication with a dispensing device such as a flexible tube for directing fluid to a desired location, such as a planting trench).
    [00073] A ball valve 1350 is preferably disposed within the low flow cavity 1310. The ball valve 1350 preferably includes a ball valve opening 1352 (e.g., a cylindrical passage opening, as per illustrated). Ball valve 1350 is preferably retained in its translational position (but being allowed to rotate as described in this document) by ball seals 1320 and 1334. Ball valve is preferably coupled to an actuator 1360 ( for example, an output shaft of an electric motor in data communication with the implement network to receive actuator positioning commands) as illustrated in Fig. 14. Actuator 1360 is preferably configured to rotate the valve of ball valve through a range of rotational movement about an axis normal to a central axis of the opening of ball valve 1352. The range of movement of ball valve 1350 when rotated by actuator 1360 preferably comprises up to a range of 360 degrees of clockwise and counterclockwise movement in the view of Fig. 13.
    [00074] The position of the opening of the ball valve 1352 preferably determines a fraction portion of a high flow passage opening 1322 and/or an outflow passage opening 1332 that are open to allow flow from the high flow passage 1320 to ball valve opening 1352 and/or from ball valve opening 1352 to outlet passage 1330, respectively. The openings are preferably shaped such that an open fraction portion of each opening increases (e.g., arithmetically, geometrically, exponentially, logarithmically) as ball valve opening 1352 rotates (e.g., in the direction counterclockwise in the view of Fig. 13) passing through each opening. For example, referring to Fig. 14, ball valve opening 1352 may have a variable width W(y) that increases (e.g., arithmetically, geometrically, exponentially, logarithmically) along the y direction. Thus, at ball valve positions that expose a vertical length y of the ball valve opening 1352, the area of the open portion O of the ball valve opening 1352 is directly related to the width W(y). In the illustrated embodiment, width W(y) preferably increases exponentially along the y direction due to arcuate (e.g., outwardly curved) sides of ball valve opening 1352. Outlet passage opening 1332 is, preferably configured similarly to the high-flow through opening 1322 except that the width of the outflow through opening preferably increases along the z direction indicated in Fig. 13.
    [00075] Referring again to Fig. 13, in a first range of partial movement of the ball valve 1350 (including, for example, a position in which the ball valve opening 1352 extends vertically in the view of Fig. 13) neither of low flow cavity 1310 nor high flow passage 1320 is in fluid communication; thus, fluid preferably does not flow to the outlet passage 1330 in the first partial range of motion.
    [00076] In a second partial movement range of the ball valve 1350 only the low flow cavity 1310 is in fluid communication with the outlet passage 1330. As a growing portion of the outlet passage opening 1332 is opened for ball valve opening 1352 (e.g. a right side thereof along the view in Fig. 13) in the second partial movement range, an increasing flow rate is allowed from the low flow cavity 1310 to the passage. outlet 1330 through ball valve opening 1352.
    [00077] In a third partial movement range of the ball valve 1350 (including, for example, the position illustrated in Fig. 13), both the low flow cavity 1310 and the high flow passage 1320 are in communication of fluids with the outlet passage 1330. As an increasing portion of the outlet passage opening 1332 is opened to the ball valve opening 1352 (e.g., a right side thereof in the view of Fig. 13) in the second strip of partial movement, an increasing flow rate is allowed from the low flow cavity 1310 to the outlet passage 1330 through the ball valve opening 1352. As an increasing portion of the high flow passage opening 1322 is opened for ball valve opening (e.g. a left side thereof in the view of Fig. 13) in the second partial movement range, an increasing flow rate is allowed from high flow passage 1320 to outlet passage 1330 through the valve opening la ball 1352.
    [00078] In a fourth range of partial movement of the ball valve 1350, only the high flow passage is in fluid communication with the outlet passage 1330. As an increasing portion of the opening of the high flow passage 1322 is opened to the ball valve opening (e.g. a left side thereof in the view of Fig. 13) in the second partial movement range, an increasing flow rate is allowed from the high flow passage 1320 to the outlet passage 1330 through the gate valve opening 1352.
    [00079] In operation, the ball valve 1350 preferably rotates continuously (counterclockwise in the view of Fig. 13) through the first, second, third and fourth partial movement bands, consecutively. The ball valve can then continue to rotate in the same direction back to the first partial range of motion or it can change direction and rotate continuously (clockwise in the view of Fig. 13) through the fourth, third, second and first partial motion ranges.
    [00080] Fig. 15 illustrates a flow device (for example, a control and monitoring unit) to control and monitor applications in a field according to a modality. With reference to Fig. 15, a flow device 600' is preferably similar to the flow device 600 described in this document, except that instead of (or, alternatively, in addition to) a flow meter disposed in the passage of high flow 610, a flow meter 1500 is arranged at inlet 604 for the purpose of measuring the total flow entering the flow device 600'. In operation of flow device 600', in a first range of flow rates (e.g., low flow rates) high flow passage 610 is preferably closed to flow and flow meter 612 is of preferably, used to determine the total flow rate through the flow device 600'. In a second range of flow rates (eg, flow rates greater than the first range), either the low flow meter 612 or the full flow meter 1500 is used to determine the total flow rate through the device. flow. In a third range of flow rates (eg, flow rates greater than the second range), the total flow meter 1500 is preferably used to determine the total flow rate through the flow device.
    [00081] The low flow meter 612 is preferably configured to measure flow accurately (for example, with .01, .05, .1, .2, .5, 1, 2, or 5% of error) in the first range of flow rates and at least a lower portion of the second range of flow rates. The full flow meter 1500 is preferably configured to measure flows accurately (for example, with .01, .05, .1, .2, .5, 1, 2, or 5% error) in the third range of flow rates and at least an upper portion of the second range of flow rates. The upper portion and the lower portion preferably overlap with the range of flow rates accurately measurable by the total flow meter 1500. A flow meter is an instrument for linear, non-linear, mass, or measurement. measurement of the flow of a liquid or gas.
    [00082] Returning to Figs. 16-20, another flow device 1600 is illustrated in accordance with an embodiment. Flow device 1600 preferably includes an inlet passage 1602, a total flow sensor 1604 for measuring a total flow through the inlet passage, a low flow cavity 1610 (preferably in fluid communication with a source of low pressure fluids), a low flow sensor 1612 for measuring a flow through the low flow cavity, a low flow path 1614, a high flow passage 1620 (preferably in fluid communication with a high fluid source pressure having a higher operating pressure than the low pressure fluid source), a high flow path 1622, and an outlet passage 1630 (preferably in fluid communication with a dispensing device such as a flexible tube for directing the fluid to a desired location such as a planting trench). In one example, the high flow passage is capable of flow rates that are up to 60 times greater than the flow rates of the low flow passage.
    [00083] A ball valve 1650 (e.g. an offset ball valve) is preferably capable of receiving a flow of liquid from the high and low flow paths and supplying the liquid flow to the outlet passage 1630 Ball valve 1650 preferably includes a ball valve opening 1652 (e.g., several cylindrical through openings as illustrated). Ball valve 1650 is preferably retained in its translational position (but allowed to rotate as described in this document) by the seals. The ball valve can be coupled to an actuator (eg an output shaft of an electric motor in data communication with the implement network to receive actuator positioning commands). The actuator is preferably configured to rotate the ball valve through a range of rotational movement about an axis normal to a central axis of the ball valve opening 1652. The range of movement of the ball valve 1650 when rotated by the actuator preferably comprises a range of up to 360 degrees of clockwise and/or counterclockwise movement in the view of Fig. 16.
    [00084] The position of the ball valve opening 1652 preferably determines a flow of liquid from the high and low flow paths through the ball valve opening to the outlet passage 1630. The openings of the flow paths are , preferably shaped such that the open fraction portion of each opening increases and decreases (e.g., arithmetically, geometrically, exponentially, logarithmically) as the ball valve opening 1652 rotates (e.g. -clockwise in the views of Figs. 17-20) passing through each opening of the flow paths.
    [00085] Referring now to a flow device 1700 of Fig. 17, in a first partial range of motion of the ball valve 1750 (including, for example, a closed position in which an opening of the ball valve 1752 has multiple openings cylinders 1751 and 1753 extend substantially vertically in the view of Fig. 17) neither the low flow cavity 1710 and the low flow paths 1714, 1715 nor the high flow passage 1720 and the high flow path 1722 are in communication of fluids with the 1730 outlet passage; thus the fluid preferably does not flow into the outlet passage 1730 in the first partial range of motion. Flow device 1700 includes seals 1754-1757 for rotating opening 1752 in ball valve 1750. Ball valve opening 1752 includes a plurality of openings 1751 and 1753 each of which has a cylindrical-shaped orifice. Apertures 1751 and 1753 are positioned relative to one another with a setting angle 1758 other than 180 degrees (for example 10-40 degrees or 20-30 degrees) which can be predetermined or adjustable according to a modality.
    [00086] With reference to the flow device 1800 of Fig. 18, in a second partial movement range of the ball valve 1850 only the low flow cavity 1810 and the low flow paths 1814, 1815 are in fluid communication with the outlet passage 1830. Specifically, the low flow paths 1817 and 1818 pass through the ball valve opening 1852 to the outlet passage 1830. As an increasing portion of an opening of the outlet passage 1830 is opened to the ball valve opening 1852 in the second partial motion range, an increasing flow rate is allowed from low flow cavity 1810 and low flow paths 1814 and 1815 to outlet passage 1830 using paths 1817 and 1818 through the opening of the ball valve 1852.
    [00087] In a third partial movement range of the ball valve 18950 (including, for example, the position illustrated in a flow device 1900 of Fig. 19), both the low flow cavity 1910 and the high flow passage 1920 are in fluid communication with the outlet passage 1930. As an increasing portion of an outlet passage opening 1932 is opened to the ball valve opening 1952 in the third partial movement range, an increasing flow rate is allowed. from low flow cavity 1910, low flow path 1914, and low flow path 1915 to outlet passage 1930 through low flow paths 1917 and 1918 passing through valve opening openings 1951 and 1953 from 1952 ball to the 1932 opening.
    [00088] As an increasing portion of an outflow passage opening 1932 is opened to the ball valve opening 1952 in the third partial movement range, an increasing flow rate is allowed from the high flow cavity 1920 and from high flow path 1922 to outlet passage 1930 through high flow path 1924 which passes through openings 1951 and 1953 from ball valve opening 1952 to opening 1932.
    [00089] In a fourth range of partial movement of the ball valve 2050 as illustrated in the flow device 2000 of Fig. 20, only the low flow paths 2015 and 2017 and the high flow passage 2020, the high flow path 2022, and the high flow path 2024, are in fluid communication with the outlet passage 3030. As an increasing portion of the high flow passage 2020 and the high flow path 2022 is opened to the ball valve opening in the fourth range of partial motion, an increasing flow rate is allowed from high flow passage 2020 to outflow passage 2030 through openings 2051 and 2053 of ball valve opening 2052. Low flow path 2014 is not in communication of fluids with ball valve opening 2052 and with outlet passage 2030.
    [00090] In operation, the ball valve (eg 1650, 1750, 1850, 1950, 2050) preferably rotates continuously (counterclockwise to the views of Figs. 17-20) through the first, second, third, and fourth partial movement bands, consecutively. The ball valve can then continue to rotate in the same direction back to the first partial motion range or can change direction and continuously rotate through the fourth, third, second and first partial motion ranges.
    [00091] Fig. 21 illustrates a flow meter with a turbine insert according to an embodiment. The 2100 turbine insert rotates as a liquid flows through the flow meter (eg 312, 322, 512, 528, 612, 628, 1500, 1612 flow sensor, etc.).
    [00092] Fig. 22 illustrates a flowmeter with a turbine insert that is coupled to a propeller component according to an alternative embodiment. Turbine insert 2200 and propeller component 2210 both rotate as liquid flows through a flow meter (eg 312, 322, 512, 528, 612, 628, 1500, flow sensor 1612, flow sensor stream 1604, etc.). The 2210 propeller component includes 2212-2215 ridges or shafts in order to obtain a faster speed and faster rotation of the turbine insert compared to a turbine insert that does not include the propeller component.
    [00093] Fig. 23 illustrates a propeller component according to the alternative embodiment. Propeller component 2300 includes crests or shafts 2302, 2304, and 2306, in order to obtain faster speed and faster rotation of an associated turbine insert compared to a turbine insert that does not include the propeller component.
    [00094] In a first embodiment, a flow device for controlling flow during an agricultural operation comprises a displaced ball valve having a plurality of openings that rotate in position to control the flow of a liquid through the displaced ball valve to a passageway. exit. A first passage provides a first flow path from an inlet to at least one opening of the displaced ball valve.
