General Monitors' Gassonic Observer Ultrasonic Gas Detector responds to the airborne ultrasound generated from gas releases in open areas
The Gassonic Observer Ultrasonic Gas Detector is designed for detecting fugitive gas leaks in compressor stations. It is a non-concentration-based gas detector used to detect leaks from high-pressure systems. It responds to the airborne ultrasound generated from gas releases in open, well-ventilated areas. Since the Gassonic Observer responds to the source of a gas release rather than the dispersed gas, it is engineered to be unaffected by changing wind directions, gas dilution and the direction of the gas leak.
The Gassonic Observer is based on microphone technology and is designed to provide a detection radius of up to 20 meters at a leak rate of 0.1 kg/s. In addition, the detector offers the Senssonic integrated acoustic self-test, which periodically verifies the integrity of the electronic circuitry and the operation of the acoustic sensor. The detector features the following approvals: CSA, FM, ATEX, IECEx and C-UL. The detector is SIL 2 suitable and is FM certified to IEC 61508.The Gassonic Observer is designed with a high pass filter to remove frequencies below 25 kHz. Setting the alarm trigger level above the ultrasonic background noise ensures immunity to other noise sources.
