Abstract: the improvement of elliptic gear measurement information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Oval gear flowmeter, for example, this paper discusses the implementation flow meter automatic calibration and the existing communication aspects of the process and the methods of the technical transformation, improve the work efficiency, to better meet the needs of current in the aspect of gas flowmeter calibration. This method. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the elliptical gear measuring improvement article details. Oval gear flowmeter, for example, this paper discusses the implementation flow meter automatic calibration and the existing communication aspects of the process and the methods of the technical transformation, improve the work efficiency, to better meet the needs of current in the aspect of gas flowmeter calibration. This method can improve the calibration accuracy and efficiency, to provide timely, accurate refueling services. 1 oval gear flowmeter the working principle of the measurement part of the oval gear flowmeter is mainly composed of two mutually meshing elliptical gear and the shell ( Measuring room) . The elliptical gear on the pressure difference of the measured medium & Delta; Under the action of p = (p1, p2, make its rotational torque. In the position shown in figure 1 a, as a result of P1 > P2, under the action of P1 and P2, joint torque generated by the clockwise rotation round 1, the round 1 and half moon containers within the medium between the shell to the export, and counterclockwise rotation driven wheel 2, then 1 primary pulley, 2 for the driven wheel. As shown in figure 1 b for the middle position, round 1 and 2 are primarily pulley wheel. In position, as shown on figure 1 c in round 1 P1 and P2 action of torque is zero, the joint torque acting in round 2 make 2 wheel counterclockwise rotation, and have to inhale half moon containers within the medium to export, then 2 main pulley wheel, wheel 1 as the driven pulley, contrary to case as shown on figure 1 a. Such a cycle, rounds 1 and 2 each other alternately by turns another 1, will be in the half moon volume measured medium again from import to export. Obviously, figure 1 week said elliptic gears by only a quarter of cases, and the discharge for a half moon volume measured medium; So, oval gear measured medium turn every 1 week produced to quality as the half moon volume 4 times, by elliptical gear meteor millions of volume flow Q: Q = 4 n & upsilon; 0 type, n for the elliptical gear rotating frequency; υ 0 for the half moon part of the volume. Thus, in the oval gear flowmeter half moon volume & upsilon; 0 given conditions, as long as the measure of elliptic gear rotational speed n can know the measured medium flow. Oval gear flowmeter flow signal ( The elliptical gear rotating speed n) With local display and remote display 2 kinds. In situ show that the rotation of the gear through a series of deceleration and adjust speed than institutions, directly connected to the instrument panel on the indicating needle, and the total amount after mechanical counter displays, as shown in figure 2. Far eastone shows mainly through the reduction gear after * magnet rotates, the spring of the relay contact with * magnet synchronous closing or opening the rotation of the same frequency, and an electrical far to another display instrument. 2 2 meter system improvement. 1 single chip microcomputer control system hardware principle of single chip microcomputer control system is mainly composed of key part, single chip microcomputer part, communication part, pulse accept part ( Count part) And the control valve of 5 parts, as shown in figure 3. The pulse signal by single chip microcomputer counter part count, PC and single chip microcomputer through the RS485 communication, valve control by electromagnetic relay. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
