Abstract: Clamp-on ultrasonic flow meters are attractive to the gas industry because they are capable of providing portable, non-invasive gas flow measurement. This paper describes the results of a Pipeline Research Council International (PRCI) funded project that addressed the ability of a clamp-on ultrasonic meter (CUSM) to measure distorted flow profiles. The test approach was to traverse a single ultrasonic transducer pair around the perimeter of the pipe in sufficiently small increments to measure the flow field at a given pipe cross section independent of the amount of flow distortion present. Detailed profile measurements at the same locations were also made with a wedge probe. The intent of this testing was to determine the accuracy with which CUSM measurements, performed with sufficient spatial fidelity, can be used to provide a reference flow rate for in-situ meter proving.
