The ability to confirm metrological parameters of ultrasonic gas meters (USMs)

The present study aims to analyze trends and prospects for the development of measurement technologies of natural gas metering by the example of ultrasonic flow meters (USM). With increasing requirements for measurement accuracy in custody transfer of natural gas, initial calibration and subsequent verification of measuring instruments in the environment as close as possible to the operating conditions is the most arguable issue among professionals. As of today, due to the functional advantages, accuracy and reliability in operation, these are ultrasonic gas meters (USMs) that have become an integral part of modern measuring units for custody transfer of natural gas.
