ABSTRACT:
A computerized leak tester system for rapidly testing a work piece for fluid leaks comprising a continuously regulated pressure supply, a coupler for connecting the pressure supply to a work piece through a valve such that the work piece is both pressurized and tested for leaks through the valve. A differential pressure transducer is connected across the valve for producing a signal in response to a differential pressure detected across the valve. A signal conversion means is provided for receiving the signal from the differential pressure transducer and for converting it into a computer readable signal. A computer is provided for receiving the computer readable signal which represents differential pressure value and for converting the differential pressure valve into a current flow rate value. Circuitry is provided in the computer for comparing the current flow rate to a predetermined flow rate value representing a maximum allowable leak rate.
