Abstract: The purpose of this presentation is to tell you about a new technique to test the accuracy of gas meters under actual operating conditions by the use of a bidirectional mechanical displacement meter prover. This is really an old technique used to lest liquid meters that has only recently been adapted to gas meters. This technique known as proving, determines a meter factor that indicates the percentage a meter is measuring over or under the true volume. The A G A Report No. 3, as a guide to good measurement, is a remarkable document. However, the use of the report does not furnish proof thai all uncertainties in gas measurement are eliminated in every case. This new technique shows how the uncertainities in measurement can be eliminated by the use of the bi-directional mechanical displacement meter prover. Tests made with a mechanical prover in gas service indicate:
