Abstract: The past several years have seen increasing use of large ultrasonic meters. In many instances these meters can handle much higher volumes than large orifice or turbine meters. A thirty inch ultrasonic meter, for example, can handle the same volume as ten twelve inch turbine meters. Such high capacity meters require specialized proving or calibration services, the first part of this paper describes the basic process of calibrating large volume ultrasonic meters. The second part briefly describes some options when a meter re-calibration is being considered.
