Public domain information on USM recalibration was reviewed. Additional publications have addressed the stability of USM’s that are permanently installed in the flow calibration loops at Certified Flow Calibration facilities.
This program is intended to improve the understanding of the stability over time of gas multi-path ultrasonic flow meters (USMs). Within the Natural Gas Industry, there are currently on universal standards requiring periodic recalibration of USMs.…
In this project, all relevant publications available since the completion of the previous PRCI recalibration research efforts (5 years) that address the stability of ultrasonic meters and the results of recalibration were reviewed. The review…
