Research on the Online Verification Instrument for Diaphragm Gas Meter

Abstract:

A novel online verification instrument for diaphragm gas meter based on positive displacement principle is proposed. Through an in-depth research on online verification technology, a dedicated wave absorber is designed to eliminate the effect of pressure pulsation. The whole series of the online diaphragm gas meter verification in normal operation condition is realized by adopting fixed-point calibration and nonlinear correction technology. The experimental data shows that the uncertainty is within 0.5% and the ratio of the measurement range is reach to 100:1.
