Leak detector is an electronic device used to sense and detect the leakage of oil & gas. These devices are installed in factories, homes, and commercial complexes, as safety systems to detect the leakage and notify the alarming situation to end-users accordingly in order to eliminate any hazardous condition. These detectors sense the gas or oil leaked and generate a signal to take proper action. Currently, in industries, leak detectors are fitted with a sound alarm to evacuate the area in case of toxic gas or oil leakage. The application of such devices is growing, due to the influx of new chemical facilities globally. Furthermore, the gas storage facility network globally has deployed a significant number of leak detectors for safety systems.
