Meter prover comprises an upstream chamber with a port and a downstream chamber with a port in which either a port for connecting to a meter. A detector unit for signalling the start and end of the proving run, and port openings at atleast one end of the piston body providing fluid communication between the chamber prior to the onset of the proving run. The piston body may be attached to a piston rod which projects through a sealing means at the end of at least one of the two chambers and is connected to the independent actuator external of the chamber.
