Experimental Research on Gear Flowmeter Based on LABVIEW

Abstract

In order to measure the dynamic instantaneous flow of the gear flowmeter, a volumetric gear flowmeter was used as the research object to simulate the measurement of the dynamic flow signal on the high pressure side. The flowmeter speed simulation experiment platform was built, and the inverter was driven by the PLC. When the inverter was activated, the inverter driven the motor to make the motor achieve different speeds, which was convenient for simulating the steady state experiment and dynamic experiment of the gear flowmeter. The program of measuring the signal of the dynamic flowmeter by using the virtual instrument was written. The response frequency of the dynamic gear flowmeter was 25Hz in the experiment. Experiments show that this measurement method is highly accurate and highly flexible, and it is easy to measure dynamic flow.
