■Working principle
The intelligent gas waist wheel flow meter is mainly composed of a shell, a conjugate rotor, a counter and an intelligent flow totalizer. A pair of conjugate rotors installed in the measuring chamber are under the action of the pressure difference between the inlet and outlet of the circulating gas (Pin>Pout), and the rotors are kept in the correct relative position through precision-machined adjustment gears. The best working gap is maintained between the rotor, between the rotor and the shell, and between the rotor and the wall plate, realizing continuous non-contact sealing. Each rotation of the rotor will output four times the effective volume of the metering chamber. The number of rotations of the rotor will be transmitted to the intelligent flow totalizer through the magnetic seal coupling and deceleration mechanism, thereby displaying the cumulative volume of the output gas. The measurement process and working principle are shown in Figure 1 (only a quarter cycle is shown in the figure).
■ The structure of the flow meter
According to the principle of electromagnetic induction, the Wiegand sensor is used to induce a pulse signal proportional to the flow and volume flow from the magnetic steel installed on the synchronously rotating gears. The signal is amplified, filtered, and shaped together with the temperature and pressure sensor signals. Enter the micro-processing unit of the intelligent flow totalizer to perform arithmetic processing, and directly display the volume flow and total volume of the gas on the LCD screen. The mechanism is shown in Figure 2.

LC series oval gear flow meter is a direct reading accumulative meter. It is a volumetric Flow meter that measures the summation of liquid flow through the pipeline. Can be widely used in petroleum, chemical, medical and health departments of the flow measurement.
The microwave pulse emitted by the guided wave radar travels along the steel cable or bar and encounters the measured medium. Due to the dielectric constant mutation, the reflection is caused and part of the impulse energy is emitted back.The height of the medium can be measured by the time interval between the transmitted and reflected pulses directly proportional to the distance between the measured medium.
The gas filter is an important equipment of the gas transmission and distribution system. In the gas transmission process, in order to ensure the normal operation and protection of the gas transmission and distribution equipment and meters such as pressure regulators, valves, flowmeters, pressure meters, etc., it must remove the solid impurities in the gas. It is necessary to install a filter with the required filtering accuracy in front of it, so our company has developed and produced the GYQ series filter specifically for the above requirements, which is applicable for natural gas,liquefied petroleum gas, city gas and other gases.
