Application of Measurement Verification Technology in Performance Evaluation of Gas Ultrasonic Measurement System

This paper introduces the measurement verification technology of the gas ultrasonic measurement system. Through a comprehensive analysis of the performance evaluation of multiple measurement stations of a natural gas pipeline company, the problems in the field measurement verification are analyzed, the measurement verification method is optimized, and the effects of sound velocity verification result overruns, temperature verification result overruns and gas quality components on sound velocity verification are investigated combined with some typical experiments. Experiments have proved that the measurement verification technology is an effective measure to ensure the accuracy and reliability of the measurement system.
