Title: The Effects Of High Pressure On Diaphragm Meter Accuracy
Author: James R. Stevenson
Source: American Gas Association 1973
Year Published: 1973
Abstract: Tests have been conducted using a 5OO cu. ft. Bell Prover to calibrate large capacity diaphragm meters. These same meters have then been operated under pressure and calibration checked by discharging into the same Bell Prover. The results confirm that meter proof is a function of meter differential pressure. Results also indicate and confirm that meters to be used under pressure should be proved at the maximum differential at which they will be used. The intent of this paper is to present the test data and show the relationship of meter proof to operating differential. The question of measurement accuracy of diaphragm meters when measurmg under pressure is not new. In fact, much work has been done to verify accuracies under varying conditions over the years. In 1939, extensive tests were conducted in Huntington, West Virginia. Some of the participants in this work were: Hope Natural Gas Company, now part of the Consolidated Gas Supply System, as well as other gas companies the West Virginia Public Service Commission: and Pittsburgh Equitable Meter, now Rockwell and American Meter Company.
