Descriptive Report of the Invention Patent for BALL VALVE AND INTEGRATED ULTRASANIC FLOW METER.
Priority application (s) [001] This PCT application is based on US N ^Q series patent application 15 / 496,078 filed on April 25, 2017, the disclosure of which is hereby incorporated by reference in its entirety.
Field of the Invention [002] The present invention relates to the field of ball valves and, more particularly, this invention relates to a ball valve that incorporates a flow meter.
Background of the Invention [003] Worldwide, drinking water and gas distribution systems use different types of pipes, valves and accessories. Most systems, even with their variations, usually include a water or gas flow meter connected to the system, for example, in a home or other facility. The flow meter measures the flow of fluid over time, which is used to charge the facility owner for the use of water and / or gas consumed at the facility. There are many different types of tubes, valves and accessories that can be incorporated into a water or gas distribution system, and different water or gas measurement technologies can be used to measure water and / or gas consumption, depending on the system . Each different type of water or gas distribution system has its own pros and cons and the choice made for any specific flow meter in a facility is often based on the price of the flow meter, the flow accuracy, the manufacturing process, ease of

2/23 installation, maintenance requirements and component size, relative pipe sizes and location.
[004] Generally, a gas or water distribution system at the facility includes a dedicated fluid flow measurement device, which normally operates in conjunction with a manually operated shut-off valve that is located before or upstream of the pressure measurement device. fluid flow to allow a technician to interrupt the fluid flow and maintain and / or replace the fluid flow meter when necessary. There are many different examples of gas and water networks that incorporate a shut-off valve adjacent to a fluid flow measurement device. Generally, domestic installations include a ball valve or a gate valve on the main gas or water line. Sometimes a switchbox holds a shut-off valve and / or water or gas flow meter and may incorporate an optional iron cover for electronic meter reading that is removed to access the shut-off valve and / or the flow meter. flow rate. A domestic water distribution system supplies water to appliances such as toilets, taps, water heaters and similar devices, and a natural gas distribution system can include a gas main with a shut-off valve and a water flow meter. gas adjacent to or in the home and the connected gas main that branches into a smaller tube to power gas appliances, such as barbecue grills, lights, pool heaters or similar components. There are problems associated with these more conventional gas and water distribution systems, such as size restrictions for various valves and fluid flow meters, unacceptable flow meter accuracy and pressure drops that occur in the gas or water distribution system that affect the accurate measurement of fluid flow.

3/23 [005] US patent 6,923,074, commonly assigned, describes a ball valve with a flow meter incorporated directly into the ball valve. The ball portion of the ball valve includes a drill hole or calibrated orifice and two positionable pressure openings placed before and after the ball, respectively, to provide indicative measurements of the flow rate of the fluid passing through the ball valve. This ball valve is generally limited to the use of water. Although it is effective for measuring fluid flow at normally higher water flow rates, it has reduced accuracy at lower water flow rates.
[006] Over the past six years, the gas and water measurement sector has improved the accessibility, performance and accuracy of ultrasonic flow meters that use transit time measurements or Doppler Effect measurements. These ultrasonic flow meters measure the amount of time required for an ultrasonic signal, for example, a ping emitted to pass between two or more fixed points within the flow meter. When ultrasonic flow meters are properly calibrated for gas and water, they can be used to measure both fluid media. Ultrasonic flow meters typically incorporate one or more ultrasonic transducers to emit ultrasonic sound waves through the fluid to determine the speed of the fluid. Since the cross-sectional area of the flowmeter body is a fixed and known value, when the fluid velocity is detected, the volume of fluid passing through the flowmeter can be calculated with very high accuracy. In addition, as fluid density changes with temperature, most ultrasonic flowmeters measure fluid temperature as a component of the volume calculation and determine fluid flow based on temperature as a variable.

When used with ball valves, ultrasonic flow meters are either connected directly to an existing ball valve or connected inside the gas or water tube to which the ball valve is connected. This can increase the ball valve and its occupied space closely linked to the ultrasonic flowmeter, that is, make the combination too large for a viable solution, making it difficult to install, maintain and replace the flow meters and valves.
Summary of the Invention [007] This summary is provided to introduce a selection of concepts which are further described further down in the detailed description. This summary is not intended to identify key or essential characteristics of the claimed object, nor is it intended to be used as an aid in limiting the scope of the claimed object.
[008] A fluid flow measuring ball valve comprises a housing with inlet and outlet openings and a valve chamber. A sphere with an orifice for the flow of fluid through it is contained within the valve chamber and the sphere has a calibrated reflector that helps the ping of the transducer to jump correctly to the ultrasonic flow meter to measure water or gas according to the most rigorous international standards. An actuator is supported by the housing and connected to the ball to rotate the ball within the housing between an open position, allowing fluid to flow through the orifice and a closed position, preventing fluid flow. A first ultrasonic transducer is positioned in the housing upstream of the sphere. A second ultrasonic transducer is positioned in the housing downstream of the sphere. The first and second acoustic reflectors are positioned inside the housing. A controller, preferably integrated with the actuator, is connected to the first and second ultrasonic transducers.
Petition 870190106908, of 10/22/2019, p. 17/69
5/23 [009] The first and second ultrasonic transducers and the first and second acoustic reflectors are aligned to transmit and reflect ultrasonic signals in at least one direction through the orifice of the sphere and, in one example, with a calibrated reflector of one transducer to another transducer when the ball is in an open position. The controller is configured to determine the fluid velocity based on the measured velocity of sound and calculate the volume of fluid that passes through the orifice based on the measured fluid velocity and the orifice cross-sectional area.
[010] In yet another example, the actuator includes a shaft connected to the ball valve and a temperature sensor carried by the shaft can be connected to the controller and configured to measure the fluid temperature. Temperature detection can assist in accounting for changes in fluid density based on temperature and determining fluid volume. Each of the first and second acoustic reflectors can comprise a vertical support upstream and downstream mounted inside the housing and with an acoustic reflector surface configured to reflect acoustic signals on an acoustic transducer or on an acoustic reflective surface, depending on the direction of transmission ultrasonic signals. The first and second acoustic reflectors can each comprise a machined surface integrated within an internal surface of the housing that is calibrated to reflect ultrasonic signals into an acoustic transducer or the surface of the acoustic reflector, depending on the transmission direction of the ultrasonic signals . A third surface of the acoustic reflector can reflect ultrasonic signals and provide various reflections.

6/23 [011] In yet another example, first and second ultrasonic transducers each can comprise transmitting and receiving circuits configured to transmit and receive ultrasonic signals. The controller can be integrated into the actuator and connected to the said drive mechanism and can be configured to determine the speed of the fluid based on the time of flight or the Doppler effect. The volume of fluid measured in an example includes the measured volume of a liquid or gas. The actuator can comprise a drive mechanism and the controller can be configured to drive the drive mechanism to rotate the ball between an open, closed or intermediate position. The controller can include a memory with a water usage signature configured for each device in a facility that has a water system to which the fluid flow measurement ball valve is connected and configured to measure water consumption within the installations.
[012] In yet another example, a fluid flow measurement ball valve comprises a housing comprising a valve body and an end adapter, both connected together and configured to form an inlet and an outlet and a valve chamber. A replaceable ball with an orifice is contained within the valve chamber. An actuator is supported by the valve body and connected to the ball to rotate the ball inside the housing between an open position, allowing the flow of fluid through the orifice and a closed position, preventing the flow of fluid. A first ultrasonic transducer is positioned in the housing upstream of the sphere. A second ultrasonic transducer is positioned in the housing downstream of the sphere. The first and second acoustic reflectors are positioned inside the housing and a controller is connected to the first and second ultrasonic transducers.

7/23 [013] The first and second ultrasonic transducers and the first and second acoustic reflectors are aligned to transmit and receive ultrasonic signals in at least one direction through the orifice of the sphere when the sphere is in an open position. The controller is configured to determine the fluid velocity based on the measured velocity of sound and calculate the volume of fluid that passes through the orifice based on the measured fluid velocity and the orifice cross-sectional area.
[014] In yet another example, the body and end adapter each include flanges and through holes that receive fasteners and align the first and second ultrasonic transducers and the first and second acoustic reflectors. The body and end adapter may include calibrated threads for mounting between them to secure the end adapter to the body and alignment marks on the body and end adapter which, when aligned, indicate that the ultrasonic transducers and acoustic reflectors are aligned.
[015] In yet another example, a water flow control system for an installation includes a water system and a plurality of devices connected to the water system. A fluid flow measuring ball valve is connected within the water system and comprises a housing with inlet and outlet openings and a valve chamber. A sphere has an orifice and is contained within the valve chamber. An actuator is supported by the housing and connected to the ball to rotate the ball within the housing between an open position, allowing fluid to flow through the orifice and a closed position, preventing fluid flow. A first ultrasonic transducer is positioned in the housing upstream of the sphere. A second ultrasonic transducer is positioned in the housing downstream of the sphere.

8/23 [016] A controller is connected to the first and second ultrasonic transducers and the first and second ultrasonic transducers are aligned to transmit and receive ultrasonic signals in at least one direction through the orifice of the sphere when the sphere is in one position open. The controller is configured to determine the fluid velocity based on the measured velocity of sound and calculate the volume of fluid that passes through the orifice based on the measured fluid velocity and the orifice cross-sectional area. The controller includes a memory with a water usage subscription configured for each device in the facility and configured to measure water consumption within the facility. A graphical user interface is connected to the controller to display the status and enter data for the water system and specific devices.
[017] In another example, the first and second transducers can align with each other and transmit and receive ultrasonic pulses without using a reflector.

Detailed Description [032] Different modalities will now be described in more detail hereinafter with reference to the accompanying drawings, in which preferred modalities are shown. Many different forms can be established and the modalities described should not be interpreted as limited to the modalities established here. Instead, these modalities are provided so that this disclosure is thorough and complete and fully transmits the scope to those skilled in the art.
[033] Referring now to Figures 1-4, a first embodiment of the fluid flow measuring ball valve is generally indicated at 20 which includes a housing generally indicated at 22 having an inlet opening 24 and an outlet opening 26, and as shown in the schematic sectional view in Figure 3, a valve chamber 28 formed inside the housing 22. This fluid flow measurement ball valve 20 will also be called a ball valve or ball valve with an integrated flow meter or an integrated ultrasonic flow meter, and all phrases refer to the fluid flow measuring ball valve 20.
[034] In this example, housing 22 is formed from two components fastened together, in this example, as a valve body 30 that forms the majority of valve chamber 28 and an end adapter 32 that connects to the valve body 30. When connected together, the two components 30, 32 form the
Petition 870190106908, of 10/22/2019, p. 23/69
11/23 housing 22 and inlet opening 24 and outlet opening 26 and valve chamber 28. Valve body 30 and end adapter 32 in this example each include extensions or flanges 34 with through holes 36 ( Figures 1, 2 and 4) that align with each other to receive the fasteners 37, which, as explained below, ensure the alignment of the different components of the ultrasonic flowmeter that are integrated within the fluid flow measurement ball valve 20. If valve body 30 and end adapter 32 are screwed together, as explained in more detail below, alignment marks can be used to align various components of the flowmeter components.
[035] Ball valve 20 may include a configuration in which housing 22 has opposite outer ends that are flanged 38 to allow a technician to insert and remove the ball valve from a pipe system (not shown) and repair or replace , when necessary, the ball or other component of the integrated flowmeter as described. Ball 40 is positioned in valve chamber 28 and can be formed as a replaceable ball. It includes an orifice or drill hole 42 that provides a fluid flow path through the ball, which is parallel to the axis of the ball valve 20. In one example, orifice 42 can be constructed to obtain a flow contraction that is calibrated for the passage of fluid passing through the ball valve 20. In addition, the cross-sectional area will be known as explained below, so that the volume of water can be calculated using the flow meter integrated into the ball valve 20. A water valve 20 may be available in a variety of cross sections, but common configurations include 1.25, 1.0 and 0.75 inch configurations.
Petition 870190106908, of 10/22/2019, p. 24/69
12/23 [036] As illustrated, an actuator 44 is supported by housing 22 and connected to ball 40 to rotate the ball inside housing 22 between an open position, allowing fluid to flow through orifice 42 and a closed position, preventing the fluid flow. This actuator 44 can be manual or automatic and can have a compartment 46 that allows a tool to be connected or a handle to leverage the rotation of the ball 40 inside the housing 22, especially in larger ball valves 20 where the rotation of the ball can be difficult due to higher water pressures and cross-sectional area. An automatic drive assembly 48 can be connected to actuator 44 to allow automatic actuation of ball valve 20 and rotation of the ball 40 inside ball valve 20. An automatic drive assembly 48 can include a gearbox, a motor electrical and associated components contained in frame 46 and an integrated controller 70, as explained in more detail below. In another example, actuator 44 includes an axis 45 with a temperature sensor function, as explained later with reference to Figures 7-12.
[037] In this example, ball joints 50 (Figure 3) help support the ball 40 within the housing 22 and engage the end adapter 32 in a pair of ball gasket recesses and the valve body 30 in another pair of ball gasket recesses. Actuator 44 includes a stem 54 that has a distal end that plugs into a groove or notch 56 of ball 40 to allow the ball to be rotated into valve chamber 28 after stem 54 is rotated through actuator 44. The stem 54 is mounted on the thrust washers in this example and includes an O-ring that helps to receive and guide the stem into a vertical hole 62 formed in the housing 22 and, more particularly, in the valve body 30 so that the distal end can be connect precisely to slot 56 of ball 40.
Petition 870190106908, of 10/22/2019, p. 25/69
13/23 [038] As shown in the sectional view of Figure 3, the orifice of the ball 42 and the proximal parts upstream and downstream of the ball in the end adapter 32 and in the valve body 30 are configured as a straight channel with the same diameter as the orifice 42 of the ball, but tapering out of the ball both in the valve body 30 and in the end adapter 32 to form end parts and a flow channel having the same diameter at both ends of the housing 22. This configuration establishes the same cross-sectional area for ball hole 42 and its immediate area, both upstream and downstream, and inlet and outlet openings 24, 26, which have a slightly larger diameter than the orifice.
[039] As illustrated in the first embodiment of Figure 1-4, a first ultrasonic transducer 66 is positioned in the housing 22 upstream of the sphere 40 and a second ultrasonic transducer 68 is positioned in the housing downstream of the sphere. In the example as illustrated, ultrasonic transducers 66, 68 are connected to a respective controller 70 which is an integral part of actuator 44 and can be connected to the drive assembly or mechanism 48 of actuator 44. In this example, depending on the design for directing the fluid flow, the first ultrasonic transducer is positioned on end adapter 32 and the other transducer 68, for example, the second, is positioned on valve body 30. Both end adapter 32 and valve body 30 can include ports of transducers that receive ultrasonic transducers 66, 68. In one example, each ultrasonic transducer 66, 68 may include a piezoelectric element as is known to those skilled in the art to generate ultrasonic pulses. In this example, each ultrasonic transducer 66, 68 can be pressed or screwed into the respective transducer port by techniques known to those skilled in the art.
Petition 870190106908, of 10/22/2019, p. 26/69
14/23 [040] This type of ultrasonic transducer includes a transmitter circuit 74 that includes a piezoelectric element in one example and an ultrasonic sensor like a receiver circuit 76. These circuits 74, 76 are configured to transmit and receive ultrasonic signals. Some ultrasonic flow meters may use one, two or more ultrasonic transducers that emit ultrasonic pulses as sound waves and include other sensors to receive pulses, but do not transmit. Other systems may use ultrasonic transducers that include transmitting and receiving circuits 74, 76 to detect and transmit ultrasonic signals and may use measurements of flight time or measurements of Doppler effect in a non-limiting example.
[041] In this example, the first and second acoustic reflectors 84, 86 are positioned inside the housing 22. In this example, the first and second ultrasonic transducers 66, 68 and the first and second acoustic reflectors 84, 86 are aligned to transmit and reflect ultrasonic signals in at least one direction through hole 42 of sphere 40 when the sphere is in the open position. Controller 70 is configured to determine fluid velocity based on the measured speed of sound and calculate the volume of fluid passing through the orifice based on the measured fluid velocity and the cross-sectional area of orifice 42 and the general fluid channel . A temperature sensor 82 is connected to controller 70 and configured to measure the temperature of the fluid and to take into account changes in fluid density based on the temperature and the determined volume of the fluid. The fluid temperature can be taken into account when determining the volume of fluid passing through the orifice. In this first embodiment, the first and second acoustic reflectors 84, 86 that are positioned inside the housing 22 include a vertical support 84a, 86a mounted in front
Petition 870190106908, of 10/22/2019, p. 27/69
15/23 to a respective acoustic transducer 66, 68, as shown in Figures 3 and 4. Each vertical support 84a, 86a includes an acoustic reflective surface 84b, 86b to reflect acoustic signals substantially 90 ° in the respective acoustic transducer positioned on the same side downstream or upstream or on another acoustic reflecting surface, depending on the direction transmitted from the ultrasonic signals. [042] As best shown in Figure 4, each vertical support 84a, 86a includes a drilled hole 84c, 86c to allow fluid to pass through each vertical support and offer less resistance to fluid flow, as the vertical support is extends upwards into the fluid channel formed by the valve body 30 and the end adapter 32. The surfaces of the acoustic reflector 84b, 86b in this example are a flat surface at 45 ° with respect to the longitudinal axis of the flow channel formed within the housing 22 and receives the ultrasonic signals and reflects them substantially at approximately 90 ° in the other acoustic reflector, or if it receives an ultrasonic signal, it reflects it substantially at approximately 90 ° in the ultrasonic transducer on the same downstream or upstream side. The vertical supports 84a, 86a can be fixed by pressure or threaded into an opening formed in the respective housing 22 opposite to the respective acoustic transducer.
[043] A second modality of the integrated ball valve and the ultrasonic flow meter 120 is shown in Figure 5. For purposes of description, common components that may differ in detail, but have common functionality, start in the number series 100. This embodiment employs a longitudinal loop 221 secured by a nut 223 in this example. It also includes an end adapter 132 and a valve body 130, but with a different configuration than shown in the first embodiment of Figures 1-4. More particularly, the valve body 130 and the
Petition 870190106908, of 10/22/2019, p. 28/69
16/23 end adapter 132 are shorter and form a more compact ball valve and an integrated ultrasonic flowmeter 120. Ball valve 120 includes the first and second ultrasonic transducers 166, 168 and transmitter circuits 174 and receiver circuits 176 Transducers 166, 168 are positioned closer to sphere 140 in this example. What is different in this embodiment is that the first and second acoustic reflectors 184, 186 are formed as a machined surface which is integrated with an internal surface of the housing 122, and in this example in particular, the internal surface within the sphere orifice 142 and aligned with ultrasonic transducers 166, 168 to reflect ultrasonic signals in a respective acoustic transducer or other acoustic reflector, depending on the transmission direction of the ultrasonic signals.
[044] In the second embodiment shown in Figure 5, the inner surface of the hole includes the first and second acoustic reflectors 184, 186 as the machined surfaces and a third acoustic reflector 187 as a machined surface that is aligned with the first and second acoustic reflectors 184, 186 to reflect ultrasonic signals and provide various reflections, in this example, four intersections or reflections. In this example, machined surfaces are formed on the inner surface of orifice 142, but can be formed on the inner surface of valve body 120 or on end adapter 132 in a non-limiting example and as shown and further explained with reference to Figures 9- 12. The ultrasonic transducer would be configured and adjusted to direct pulses in one direction to the acoustic reflectors and thus the alignment becomes more critical and the alignment is done through precise alignment lines and marks, as explained below. Different machines can be used to machine the housing and other elements, such as machined reflectors, including a
Petition 870190106908, of 10/22/2019, p. 29/69
17/23 transfer, a CNC machine, single or multiple spindle machines. Different materials can be used for different components, but normally the valve body 130 and the end adapter 132 are made of forged nickel plated ball. Actuator 144 and stem 154 can be formed from a machined brass bar. This construction can be applied to all the modalities of Figures 1-6.
[045] Since the alignment of the transducers and any reflectors must be accurate, it can be difficult to ensure that ultrasonic transducers 166, 168 and acoustic reflectors 184, 186, 187 are on the axis or alignment to send and receive ultrasonic pulse signals with acoustic reflectors and therefore the valve body 130 and end adapter 132 use calibrated threads 190 to hold the two components together and ensure alignment between the transducers and reflectors. The use of nuts and bolts with flanges 34 and through holes 36 shown in Figures 1-4 can guarantee alignment, but in this particular example in Figure 5, the alignment of the transducers and reflectors can be done using the calibrated threads 190 and alignment marks 192 on end adapter 132 and valve body 130 to ensure alignment. Different machines as noted above can be used in the manufacture of components and threads, but in one example, the automated machine with CNC control can make the specific number of thread turns required for ball valve 120 with its valve body 130 and end adapter 132 screwed and secured and aligned with alignment marks 192. Thus, both transducers would be aligned with any reflectors. The precise assembly can also be tested by aligning the alignment marks 192 along the valve body 130 and end adapter 132 and testing when no fluid flows.
Petition 870190106908, of 10/22/2019, p. 30/69
18/23 [046] In the third modality shown in Figure 6, which has reference numbers in the 200 series, the first and second ultrasonic transducers 266, 268 are aligned with each other without the use of acoustic reflectors, so that a transducer will emit pulses that point to the other transducer. Alignment is ensured by proper measurement of the calibrated thread of screw 290 with the specific number of turns and the use of alignment marks 292 along the valve body 230 and end adapter 232, so that, when aligned, the two transducers ultrasonic 266, 268 will be in direct alignment with each other.
[047] Referring again to the modality shown in Figure 5, it is possible to generate a number of ultrasonic pulses that pass through the valve 120 through the machined acoustic reflectors, which are designed and configured to be two, three or four intersections, with four intersections shown in the embodiment of Figure 5. For example, orifice 142 has an internal surface as described above and yet another machined surface integrated into the internal surface and forming the third acoustic reflector 187 which is aligned with the first and second acoustic reflectors 184, 186. Although these machined surfaces are shown in the orifice, they can be machined in other positions within the housing 122 on the valve body 130 or on the end adapter 132. Ball 140 would be precisely aligned, just like precise alignment using the ball gasket 150 and connection through slot 156. If any reflector is machined on the inner surface of sphere 140, the ball alignment through notch 156 and alignment of valve body 130 and end adapter 132 will become more essential.
[048] In operation, the ball valve 20 that has the ultrasonic flow meter using ultrasonic transducers 66, 68 and
Petition 870190106908, of 10/22/2019, p. 31/69
19/23 any acoustic reflectors 84, 86 can average the speed of sound through several paths, but it usually works by generating the ping with the transducers and measures the time that elapsed before the other transducer (or sensor) receives the sonic pulse. The ultrasonic paths can point upstream in an example, so that the sum of the flight times of the sonic pulses can be divided by the sum of the flight links and provide an average speed of sound in the upstream direction.
[049] The 20 ball valve that has the integrated ultrasonic flow meter as explained can also use Doppler effect measurements to determine the speed of the water that passes through the valve, or in another example, the transit time that measures the quantity of time required for an ultrasonic signal to pass between two or more fixed points inside the ball valve 20. When using the Doppler effect, on the other hand, the frequency of a reflected wave is different due to the Doppler effect. When the fluid moves faster, the frequency change increases linearly and the controller 70 processes signals from the transmitted wave and its reflexes to determine the flow. When using a transit time system, the transducers will send and receive ultrasonic waves between the transducers in both the upstream and downstream directions. In no flow condition, it is the same time to travel upstream and downstream between transducers 66, 68, but under flow conditions, the upstream pulse will travel more slowly and take longer than the fastest downstream pulse. As the fluid moves faster, the difference between the upstream and downstream pulse times increases and the controller 70 will process the upstream and downstream pulse times to determine the flow.
[050] The path between the first and second transducers 66,
Petition 870190106908, of 10/22/2019, p. 32/69
20/23 through the first and second acoustic reflectors 84, 86, as shown in Figures 1-4, for example, is a single path and forms a single path sensor, but the ball valve with its ultrasonic flowmeter 20 can be designed for multiple paths. Typically, as the first pulse is generated from an ultrasonic transducer 66, a start signal can be generated at controller 70 to mark the start of a flight time measurement. In the second ultrasonic transducer 68, the pulse is received and the controller 70 generates a stop signal to mark the time when the ultrasonic pulse was received. The time required for the pulses to travel from one transducer to the next, that is, the time between the start pulse and the first stop, is the flight time. When a pulse signal is received on the other transducer, by reflection, as in Figures 1-5 or by direct pulse generation to the other transducer, as in Figure 6, that receiving transducer can switch to transmit a set of ultrasonic pulses that are received by the other transducer via reflex or direct and form a new flight time. The difference between the two flight times is proportional to the speed of the flow of the medium, fluid or gas in the valve. There may be a calibration factor depending on the type of machining and configuration of the ball valve. This calibration can be performed in advance, before being connected to the fluid flow.
[051] The average speed of the fluid flow is taken into account and the cross-sectional area of the orifice and other parts of the ball valve are taken into account.
[052] It is also possible that the ball valve and the integrated ultrasonic flowmeter 20 can be formed as a non-invasive Doppler flowmeter that requires particles or bubbles in the flow, such as those used in wastewater applications or
Petition 870190106908, of 10/22/2019, p. 33/69
21/23 conductive or water-based dirty liquids. The frequency shift or Doppler effect can use a physical sound wave that changes the frequency when it is reflected by discontinuities in motion in the flowing liquid and the discontinuities reflect the ultrasonic pulses with a slightly different frequency that is proportional to the flow rate of the liquid . In one example, the fluid must contain at least 100 parts per million (PPM) of particles or bubbles in suspension of 100 microns or larger. An ultrasonic transducer that has both the transmitting circuit and the reflecting circuit can be used by two ultrasonic transducers.
[053] As noted earlier, shaft 45 may be part of actuator 44 Axle 45 may include Ο-ring's 45a that allow the shaft to rotate within housing 22. A projection 45b at the distal end of shaft 45 connects to a notch in ball 40, so that when the axis is rotated, the ball also rotates. The axis 45 may include a temperature sensor 82 that extends through the axis that allows temperature detection. It can include a channel that allows the flow of fluid in the channel to allow the detection of temperature closer to the actuator and the integrated controller 70.
[054] Figure 8 shows the axis 45 received inside the housing 22. Figures 9 and 10 are other cross-sectional views showing the axis 145 received inside the valve body 130 in a modality that includes the machined acoustic reflective surfaces 184, 186 , as best shown in Figures 11 and 12. The surfaces of the machined acoustic reflector 184, 186 are calibrated and positioned as at a 30% or 45% angle or another angle to ensure that the ping from the transducers bounces correctly. In this modality, the first and second acoustic reflectors appear 184, 186, are machined in the body outside the sphere area and the third surface of the 187 acoustic reflector can
Petition 870190106908, of 10/22/2019, p. 34/69
22/23 be machined at the end of the shaft in an example or on the inner wall of the hole.
[055] Figure 13 shows a high-level diagram of a water flow control system 400 (numbers start in the 400 series) for installations such as a 402 home where the facilities include a 404 water system that includes the valve sphere 420 as described above, having a water main 406 and a plurality of devices 408 connected to the water system, such as a washing machine, bathrooms, showers, water heater and other devices that use water. Controller 470 may include memory 471 with a water usage signature configured for each device 408 to which the fluid flow measuring ball valve 420 is connected and configured to measure water consumption within the facility. In this example, a 473 graphical user interface is connected to the 470 controller and displays the status and allows data entry to the water system. It also includes device-specific signatures. System 400 can connect to a portable communication device 410, such as a cell phone. A 411 GUI can be located on the phone to display status or enter data.
[056] For example, the ball valve with integrated flow meter 420 can measure water consumption inside the apartment, house or residence from a single point. With a specific algorithm that can be customized for specific installations, the configuration and consumption of water (or gas, if used as a gas ball valve and flow meter) are registered as a subscription for each specific device and the system can register and classify water and gas consumption within the facility. The 470 controller can be self-instructed using water / gas in real time divided for each device or accessory
Petition 870190106908, of 10/22/2019, p. 35/69
23/23 plumbing. In effect, this system allowed for a water balance and an affected water quantity. Thus, greater control over consumption can be planned and the devices adjusted accordingly.
[057] Many modifications and other modalities of the invention will come to the mind of a person skilled in the art, having the benefit of the teachings presented in the previous descriptions and the associated drawings. Therefore, it is understood that the invention should not be limited to the specific modalities disclosed and that modifications and modalities are intended to be included in the scope of the appended claims.
