Abstract
A system for in situ testing of fluid meters is disclosed in which a single dual-position valve is disposed in series with and downstream of the meter to be tested in the supply line. In the first position, the inlet and outlet openings of the valves are such that a fluid is enabled to pass straight through the valve along the supply line and in a second or test position, the upstream and downstream openings of the supply line to the valve are in communication with auxiliary ports not connected with each other enabling a test or calibration unit to be connected in series with the auxiliary test ports. In this manner, testing of the meter is accomplished without interruption of the gas supply to the user.
