Description:Gives guidance for the design, installation and calibration of pipe provers. Applies to pipe provers for use with different liquids and types of meters and for proving them in different services. Does not apply to the newer "small volume" or "compact" provers. Includes references, definitions, description of systems, essential performance requirements, equipment, design of pipe provers, installation and calibration.
