Commentary on differential-pressure measurements at high reference pressures
Abstract
Some practical approaches to the difficult problems in calibrating and implementing differential pressure measurements are discussed. The data presented were gathered several years ago in separate investigations. An attempt is made to compare the results of these investigations to the common mode concept as described by Peter K. Stein in his publication, "The Measurement of Differential Quantities - Problems and Approaches." Although one of these investigations involved a 10,000 to 20,000 psi reference-pressure gas measured at an ambient temperature and the other a classic delta P flow measurement of cryogenic temperature, the problems encountered were the same.
