Explanation
A detection method for detecting the leakage of gas or liquid from or into a sealed container by surrounding its outer surface, determining the location of the leakage point, and estimating the leakage rate. leak testing is carried out according to the principle that fluid flows out of the leakage channel due to the different pressure inside and outside the sealed container. Multiple methods can be used, such as acoustic method, bubble method, flow rate method, chemical reaction method, halogen gas method, pressure difference method, etc.
