Onsite proving of gas turbine meters

摘要

This paper examines a patented mobile gas turbine meter proving system that blends technology from liquid turbine meter provers with innovative ideas that particularly apply to gas measurement. Arkla Pipeline Group developed and now uses this mobile sonic nozzle prover on gas turbine meters ranging in size from 3 "thru 16" at meter station sites under actual operating conditions. The prover also incorporates a gas chromatograph which uses the actual mass flow computations.
