2. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   Chris Cassidy works with an ultrasonic leak detector on the International Space Station. Escaping liquids create an acoustic signal as they pass through a hole in the pipe. Acoustic sensors affixed to the outside of the pipeline can create a baseline acoustic "fingerprint" of the line from the internal noise of the pipeline in its undamaged state.

3. Tracer-gas leak testing - Wikipedia

   en.wikipedia.org/wiki/Tracer-gas_leak_testing

   As well as airbags, the air conditioning system, fuel system, and exhaust system require testing for leaks. Pacemakers and catheters have to be tested for efficacy and longevity. On planes, tracer-gas leak testing is used to quickly and safely locate fuel leaks, [ 3 ] as well as to check oxygen distribution devices and cabin pressurization systems.

   The ultrasonic gas leak detector then produces an alarm when there is an ultrasonic deviation from the normal condition of background noise. Ultrasonic gas leak detectors cannot measure gas concentration, but the device is able to determine the leak rate of an escaping gas because the ultrasonic sound level depends on the gas pressure and size ...

5. Helium mass spectrometer - Wikipedia

   en.wikipedia.org/wiki/Helium_mass_spectrometer

   The vacuum chamber is connected to a vacuum pumping system and a leak detector. Once the vacuum has reached the mass spectrometer operating pressure, any helium leakage will be measured. This test method applies to a lot of components that will operate under pressure: airbag canisters, evaporators, condensers, high-voltage SF 6 filled switchgear.
