ABSTRACT:
A dynamic leak detector is connected to a fluid flowmeter prover. The prover has a measurement chamber with a fluid inlet and a fluid outlet and a barrier which moves axially through the chamber between the fluid inlet andc the fluid outlet. First and second spaced apart seals between the barrier and the chamber interior prevent fluid from passing through the barrier. The leak detector is connected to the space between the first and second seals and urges fluid to flow out through the seals into the chamber, while the prover is operating. If more than a threshold amount of fluid passes through the seals during a test run, the operator is alerted and the test run is rejected.
