A Method for Maintaining Accuracy of Ultrasonic Gas Flow Meters Calibrated on Air at Atmospheric Pressure when Measuring Natural Gas at High Pressure

A. Stetsenko, V. Naumenko

Abstract

With the increase in the requirements for the accuracy of measurement in the commercial accounting of natural gas, the issue of initial calibration and periodic verification of measuring instruments in conditions as close as possible to actual working conditions is relevant and commonly discussed among professionals. This issue also applies to ultrasonic gas meters. Despite the general tendency to calibrate (verify) ultrasonic gas meters at operating conditions, this requirement is not always appropriate. First of all, this is due to the high cost of calibration services and the insufficiently developed network of accredited calibration laboratories. The issue of determining the rules and criteria for justifying the need to calibrate ultrasonic gas meters at operating conditions remains extremely concurrent.
