FUNDAMENTALS OF ULTRASONIC FLOW METERS

Abstract

SUMMARY This paper presents an outline of the operating principal and application of ultrasonic gas flow metering for custody transfer. Basic principles and underlying equations are discussed as are considerations for applying ultrasonic flow meter technology to station design, installation and operation. These applications are illustrated based on operating experience with the Instromet 3 path and 5-path Q.Sonic custody transfer flow meter, however, many of these issues may be generalized to devices manufactured by others.
