چکیده
This paper outlines the operating principles 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 SICK ultrasonic flow meter, however many of these issues can be generalized to other meter manufacturers.
