Abstract: The use of liquid ultrasonic meters for liquid petroleum applications such as custody transfer or allocation measurement is gaining worldwide acceptance by the oil industry. Ultrasonic technology is well-established, but the use of this technology for custody transfer and allocation measurement is relatively new, and users often try to employ the same measurement practices that apply to turbine technology. There are some similarities between the two approaches, such as the need for flow conditioning and upstream and downstream piping requirements, but there are also differences, like the proving technique or field validation procedure. This paper will discuss the various in-situ proving methods that can be used for successful field calibration of a liquid ultrasonic meter
