Abstract: The need for calibrating flow meters of various types for gas service at elevated pressures is well documented. Currently various forms of Bell Provers or volumetric type glass tubes are used as primary standards at or near atmospheric pressure with reasonable precision, and nozzles or venturies are used at elevated densities. In many cases the flowmeter being calibrated has the potential of being more precise than the standard its being calibrated against. Flow Technology, Inc. has developed a primary positive displacement volume-time standard capable of calibrating flow meters at any desired density up to pressures of almost 1500psia. Almost any media can be used in the system.
