Research and analysis of sensor performance in gas well flow measurement

In all links of natural gas supply, storage and marketing, accurate measurement of flow is one of the most critical links. Due to the high requirements of gas flow measurement for the flow meter measurement system, not only high accuracy of the flow meter measurement is required, but also higher requirements for the measuring sensor. Therefore, this paper mainly studies the influence of sensor structure design and sensor drive waveform on the signal sent and received by the gas flowmeter in the process of natural gas supply. Through the analysis and research of the ultrasonic attenuation theory, the conclusion that the performance of the oblique probe sensor is better is obtained. And by analyzing the experimental data, it is verified that the sensor effect of the oblique probe driven by the pulse waveform in the driving circuit is the best.
