Test procedures help ensure accuracy of orifice meters.

From: Pipeline & Gas Journal | Date: July 1, 1996| Author: Fillman, Curtis R. | Copyright information

The petroleum industry has long been using orifice meters to measure differential pressure, static pressure and temperature. Consisting of a plate/tube and recorder, these meters require minimum maintenance and accurately measures a wide range of flow rates. However, the accuracy of these meters depends largely on the quality of their calibration devices. A meter test consisting of meter calibration, orifice plate inspection, quality of gas tests and test report to verify the data is needed t...
