Accuracy: Some LDS are able to calculate leak flow and leak location. This must be done accurately. Robustness: The LDS should continue to operate in non-ideal circumstances. For example, in case of a transducer failure, the system should detect the failure and continue to operate (possibly with necessary compromises such as reduced sensitivity).

A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.
Another test is for duct leakage to the outside. Depending on the location of the house in the United States, some HVAC systems are completely inside the thermal envelope, some are completely outside the thermal envelope, and some are a combination of the two. Energy conservation is improved mostly by sealing ductwork that is outside the ...

Typically a helium leak detector will be used to measure leaks in the range of 10 −5 to 10 −12 Pa·m 3 ·s −1. A flow of 10 −5 Pa·m 3 ·s −1 is about 0.006 ml per minute at standard conditions for temperature and pressure (STP). A flow of 10 −13 Pa·m 3 ·s −1 is about 0.003 ml per century at STP.
