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