Abstract
A testing device and method for improved detecting of fluid leaks considered important, for example, fluid leaks that would be external to a component or machine are disclosed. The testing device includes a conventional infinite fluid pressure supply source which supplies equal fluid pressure to a reference volume zone, a critical zone and an internal zone, the critical zone and internal zone may be positioned inside of a device being tested.
Claims15
A fluid leak testing device comprising:
- a source of pressurized fluid;
- a pressure regulator in fluid communication with the source;
- a first mass flow meter in communication with the pressure regulator;
- a second mass flow meter in communication with the pressure regulator;
- a reference zone tank in fluid communication with the pressure regulator via the first mass flow meter;
- a first fluid line in communication with the pressure regulator via the second mass flow meter, the first fluid line adapted to be sealingly connected to a critical zone of a test device being tested;
- and
- a second fluid line in communication with the pressure regulator, the second fluid line adapted to be sealingly connected to an internal zone of the test device.

A method for measuring a fluid leak in a test device having a critical zone and an internal zone, the method comprising the steps of:
- generating a pressurized flow of fluid at a predetermined fluid pressure;
- transferring the pressurized flow of fluid at the same fluid pressure to a reference zone, the critical zone and the internal zone, the critical zone and the internal zone positioned within the test device;
- monitoring and measuring an environmental effect value from the reference zone;
- monitoring and measuring a flow of the pressurized fluid to the critical zone;
- and
- determining an actual leakage value of the critical zone.
