Abstract

Outlines static and dynamic metering systems to measure gas in 0.350 to 0.637 grams per c.c. range. Serves as a guide in the selection, installation, operation, and maintenance of measuring systems that apply to liquefied petroleum gases and includes functional descriptions for individual systems. Coverage includes elimination of swirl, temperature measurement, pressure measurement, measurement by orifice meter, measurement by turbine meter, density determination, tank calibration, and special precautions for mass measurement.
