    1492004 Gas meters I J GRZESLO 16 March 1976 [20 March 1975] 10537/76 Heading G1R A device for correcting the indicated reading of a flowmeter for temperature includes a pivoted member 42 which is driven to oscillate between a pre-set point and a cam 53 which is moved by temperature sensing means 51, the member being driven by the flowmeter and its output drives a counter 50. The meter output drives a gear train including shaft 28 to which wheel 29 is attached. The wheel carries a pin 30 which passes through a slot in an arm 32 pivoted to the member 42 at 41. A block 37 is attached to the pin and is guided by rod 39 sliding in a projection 34, and is spring- loaded. This allows motion to be lost once the member 42 reaches the cam. The member 42 is connected via a one way clutch 44 to the counter. The gear train drives a counter directly to provide an uncorrected reading; a pointer extends from counter 50 to the cam to indicate temperature.

    (54) DEVICE OF TEMPERATURE IMPACT OF COUNTERS. GAS VOLUME The invention relates to measurement technology, and more specifically to devices for compensating the temperature error of a gas quantity counter. A device for temperature compensation of a gas quantity counter is known, comprising a counter output shaft connected through a reducer to a first recorder, a thermosensitive element with a cam working surface, a drive wheel connected to a hammer, and a second recorder connected to it. In this device, the cam element is forcibly moved in only one direction and is associated with a spring moving it in the downstream direction. Such a connection is unreliable and reduces the TOjjjHocTb counter reading. . The proposed device is equipped with a rocker arm, is pivotally connected to a cam drummer, and the front surface of the drive wheel is provided with an eccentric, which is inserted into a slot made in the body of the rocker arm. Moreover, the contacting workers of the cam drummer and the thermo-sensitive laser are rough. FIG. 1 and 2 shows a structural diagram of the device. The device comprises a casing 1 with a flange 2. Inside the casing there is a housing 3 attached to a pipeline through which the measured flow flows (not shown in Figs. 1 and 2). The housing 3 includes side walls 4 and 5, a shaft 6 is supplied to the inside of the housing 3, equipped with a worm gear 7 and 8. The shaft 6 is rotated by a volume counter from the measured flow (the counter and its drive are not shown). Through gears 7, 8; 9 -11 12, 13 and 14, 15, fixed cootBeTCtBeHHO on the shafts, the ends of which are installed in the side walls 4 and 5 of the housing 3, the rotation is transmitted to the revolution counter 20.; Thus, the rev counter registers the flow volume without taking into account the change in its temperature. The end 21 of the shaft 19 is extended through the side wall 5 and is equipped with a wheel 22 with an eccentric 23, which is inserted into the slot 24 of the link lever 25, on
    the ends of which have protrusions with perforations 26 and 27. A threaded screw 28 with a spring 29 located between its head and the protrusion 26 is screwed through a threaded hole in the protrusion 26. A stop sleeve 30 is put on the screw 28 into the hole through the slit 24 and the gasket 31 The eccentric 23 enters. The upper or lower end 32 of the screw 28 passes through a hole in the protrusion 27 and is enclosed by a spring 33 placed between the sleeve 30 and the protrusion 27. The upper end of the hinge 34 is connected to the cam by a hammer 35 pushed onto one end of the shaft 36, installed in The touch wall 5.
    drummer 35 through the shaft 36 is connected to the clutch overtaking 37 and provided with a radial lever 38 with a protrusion 39, covered by a plastic sleeve 40.
    On. the second end of the shaft 36 is fitted with a gear wheel 41, which is engaged with the wheel 42 of the second rev counter 43.
    Bimetallic spiral (thermo-sensing element) 44 oh, rolls in the rod 45, connected to: cam 46 having a front toothed surface 47 and side surface with a scale of 48.
    The cam 46 is designed in such a way that its cam-cam-like surface 47 contacts the cam 39 protrusion 35, the pointer 49 connects the speed indicator 43 and the scale 48 so that the cam 46 rotates through a certain angle corresponding to the specific value of the measured flow temperature and perceived bimetallic spiral 44. In this case, the pointer 49 shows the corresponding temperature value on the scale 48
    The device works as follows.
    The measuring tube, passing through the counter, rotates the ert) impeller, and it drives the shaft 6
    With shaft 6 through gears 7, 8; 9 - 11 12, 13; 14, 15 and, accordingly, the shafts 16 -19 rotation is transmitted to the revolution counter 20, which measures the gas passing through it without taking into account the measurement of its temperature. The rev counter 20 is the first recorder 4 and the EV is engaged with shaft 6.
    The bimetallic coil 44 is a temperature sensor with measured flow passing through the meter, and causes the rod 45 and cam 46 to rotate when the temperature of the flow changes. The rotation of the cam 46 and its face surface 47 causes the rotation of the striker 35 along the corresponding arc.
    The 19 is driven by a gear from shaft 6 such
    that the wheel 22 rotates counterclockwise. When it rotates, the eccentric 23 rotates around the continuation of the shaft 21, raises and lowers the rocker lever 25, causes the cam drummer 35 to move. When the wheel 22 rotates from the position shown in FIG. 1, in the direction of the position shown in FIG. 2, the eccentric 23 lifts the lever 25 under the stop sleeve 30 and the movable spring 33 to the upper protrusion 27. Such movement and compression cause the impactor 35 to rotate relative to the shaft 36 from the position shown in FIG. 1 to the position shown in FIG. 2, in which the friction surface of the sleeve 40 on the protrusion 39 of the cam impactor 35 contacts the corresponding location of the cam surface 47, which depends on the temperature of the flowing gas. If the rocker lever 25 continues to press the cam drummer to the right, as shown in FIG. 2, after contact with the cam surface 47, due to the rotation of the wheel 22, the movement is absorbed due to the loss of movement of the rod 32 further through the hole in the upper lip 27 of the lever 25, overcoming the resistance of the spring 33 when the eccentric 23 moves further along the groove 24.
    When the eccentric 23 on the wheel 22 rotates further counterclockwise, it and the sleeve 30 associated with it turn the lever 25 back down until the sleeve 30 contacts the end of the set screw 28. When it contacts the screw 28, he through the lever 2 5 will take the drummer 35 away from the end surface of the cam 47 to the position shown in FIG. 1 Then the cycle is repeated, causing the cam drummer 35 to oscillate in an arc. Thus, the set screw 28 is a stop limiting oscillations along the arc of the cam hammer 35 at one end, and at the other end the limitation occurs due to the end cam surface 47.

    When the hammer 35 oscillates, the overtaking clutch 37 is disconnected during the movement to the right (see Fig. 1 izepsepl while moving to the left, turning the shaft 36 and the counter 43. Thus, the counter 43 records oscillations along the arc of the cam hammer 35 in one direction the arc length of which is determined by the installation of the screw 28 and the temperature received and recorded by the cam surface 47. The set screw 2B is initially adjusted to calibrate the temperature compensator. The cam hammer is operated in two directions x, in contact with the cam surface and vice versa, using a lever 2 driven by wheel 22 and shaft 21. Invention 1.
