What is Gas Detection?
Gas leak detection can be done by use of various methods.
Traditionally methods include Catalytic/IR Point Sensors and IR Open Path Sensors, more recent detection methods include Ultrasonic Gas Leak Detectors.
In order to detect gas leaks with traditional methods, the gas itself must either be in close proximity to the detector or within a pre-defined area. Outdoor environmental conditions such as changing wind directions and quick dispersion of a potential gas cloud, which can be found e.g. on an offshore platform, can result in undetected gas leaks, leading to extremely dangerous situations.
An alternative to these traditional detection methods is ultrasonic gas leak detectors. This detection method often use a microphone technology; which detect outdoor leaks by sensing the distinct high frequency ultrasound emitted by all high pressure gas leaks, meaning that the gas does not have to reach the sensor - just the sound of the gas leak.
