Ultrasonic gas leak detection technology detects leaks from pressurized gas systems by sensing the airborne ultrasound produced by the escaping gas. They detect gas leaks at the speed of sound in a detection radius up to 20 meters. Ultrasonic gas leak detectors do not have to wait for the gas to accumulate into a potentially dangerous gas cloud and come into physical contact with the detectors. They are unaffected by conditions such as changing wind directions, gas dilution, and the direction of the gas leak - conditions relevant for most outdoor gas installations. They instantaneously raise an alarm if a leak is detected. The Gassonic ultrasonic gas leak detectors have a worldwide installation track record of more than 3000 units offshore and onshore in the petrochemical industries.
