Abstract: As the price petroleum products increase in the world market, the need to accurately measure escalates. Even seemingly small measurement errors can add up to millions of dollars over just a few months. Dynamic measurement with flow meters has played an important part in the accurate measurement of petroleum products since the mid 1930s. Initially Positive Displacement meters were the only devices approved by the American Petroleum Institute (API) for the custody transfer of petroleum products. Later, in the early 1970s, the API issued the Turbine Meters Standard, which was used for refined products and light crude oils. More recently, the helical turbine meters were introduced to measure more viscous products. Most recently API Standard 5.6 Measurement of Liquid Hydrocarbons by Coriolis Meters (2002) and API Standard 5.8 Measurement of Liquid Hydrocarbons by Ultrasonic Flowmeters Using Transit Time Technology ( 2005) were issued. Choosing the right meter and verifying the meters performance over the flow and product range is important for an accurate, trouble-free custody meter application. Verification of performance on hydrocarbon products of like characteristics by the manufacturer is an important step in this process. The details of this critical step in the custody meter manufacturing process are the subject of this paper.
