This document provides descriptions of the different types of pipe provers, otherwise known as displacement provers, currently in use. These include sphere (ball) provers and piston provers operating in unidirectional and bidirectional forms. It applies to provers operated in conventional, reduced volume, and small volume modes. This document gives guidelines for: \u2014    the design of pipe provers of each type; \u2014    the calibration methods; \u2014    the installation and use of pipe provers of each type; \u2014    the interaction between pipe provers and different types of flowmeters; \u2014    the calculations used to derive the volumes of liquid measured (see Annex A); \u2014    the expected acceptance criteria for fiscal and custody transfer applications, given as guidance for both the calibration of pipe provers and when proving flowmeters (see Annex C). This document is applicable to the use of pipe provers for crude oils and light hydrocarbon products which are liquid at ambient conditions. The principles apply across applications for a wider range of liquids, including water. The principles also apply for low vapour pressure, chilled and cryogenic products, however use with these products can require additional guidance.<\/p>\n
