ABSTRACT:
An automated calibration apparatus and method for calibrating a fluid piping system leak detector uses a calibrated leak device with an orifice that releases fluid at a constant calibrated leak rate. The calibrated leak device is connected to the fluid piping system and a pump is activated to pressurize the fluid piping system. The pump is deactivated, and pressure decay in the fluid piping system resulting from fluid release from the calibrated leak device is measured. The leak sensitivity of the leak detector is then adjusted based on the measured pressure decay versus time with the calibrated leak.
