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: — the design of pipe provers of each type; — the calibration methods; — the installation and use of pipe provers of each type; — the interaction between pipe provers and different types of flowmeters; — the calculations used to derive the volumes of liquid measured (see Annex A); — 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).
