Fast Ultrasonic Leak Detection Offers Extra Layer of Protection

Hydrogen is a lighter than air gas and consequently challenging to detect in open, well ventilated areas. It a combustible gas that is difficult to detect and easily ignitable on contact with open flames, electrical sparks, and static discharge.

Traditional gas detection systems (infrared and catalytic point and open path gas detection) rely on a concentration build up of the leaking gas to enable detection. These systems work fairly well in closed or indoor installations, but in outdoor, ventilated areas such as offshore platforms, many gas leaks can go undetected for long periods of time. The problem is, that due to the nature of these systems, the gas needs to be in physical contact with the sensor or within the path of an infrared light beam before it can be detected. In outdoor installations, this is very difficult to ensure as the leaking gases are rapidly diluted or blown away by the wind.

Gassonic has now introduced a fast ultrasonic gas leak detection with a new layer of protection that reduces the risk of gas leak and fire ignition hazards. When combined with General Monitors' gas and flame detection solutions, ultrasonic technology enhances hydrogen detection efficiency, increasing the likelihood that a hazard is mitigated before it escalates.

Advanced ultrasonic technology quickly detects the ultrasonic noise generated by the escaping gas at a distance from the leak source. A distinct advantage of the technology is that it detects the gas at leak initiation regardless of ventilation rate, gas dilution, or the direction of the leak – and without the gas having to make physical contact with a sensor element. This makes it the ideal choice for rapid detection of pressurized hydrogen leaks in vessels and pipes in open and ventilated areas.

The Gassonic Observer detector is designed on robust microphone technology. Its detection radius for hydrogen is up to 8 meters at a leak rate of 0.01 kg/s. In addition, the Gassonic Observer features the Senssonic™ integrated acoustic self-test, which periodically verifies the integrity of the electronic circuitry and operation of the acoustic sensor. The detectors are SIL suitability rated and hold relevant C-UL and ATEX certifications.
