OBSERVER-i Ultrasonic Gas Leak Detector

The OBSERVER-i is a third-generation ultrasonic gas leak detector for quick gas leak detection under pressure (from 2 bar). It is the first ultrasonic detector equipped with an artificial neural network (ANN) that uses patented technology to detect only gas leaks by suppressing unwanted background noise.

  • Quickly detects leaks of all gases under pressure (2bar)
  • Wide detection range while maintaining immunity to false alarms
  • Consistent detection coverage up to 28 metres away
  • Patented and proven Senssonicâ„¢ self-test function
  • A very cost-effective solution in the open air where conventional detectors are ineffective
Additional information

Technologies traditionally used in fixed installations to detect hydrocarbon gas leaks (such as catalytic, infrared, and infrared linear barrier sensors) have a shared limitation. For leak detection, the gas must be near the detector or in a predefined area.

Unfortunately, external environmental conditions such as a change in wind direction and rapid dispersion of the gas cloud escaping from an outdoor installation can cause gas detection to fail because the gas never reaches the detector!

Ultrasonic gas detection uses acoustic sensors to identify noise fluctuations that are not audible to the Human. The leak produces a broadband acoustic noise when gas under pressure escapes, which covers audible frequencies down to the ultrasonic frequencies.

In addition to the fact that this type of acoustics-based technology is little affected by changes in wind direction (unless there are strong headwinds), gas dilution, or the direction of the gas leak, it is not gas discriminating. Therefore, we can use it to detect hydrocarbon leaks.

Finally, we will no longer speak of point gas detectors but monitoring zones. The OBSERVER-i, with its advanced technical performance, will react instantly when a gas leak occurs, at distances of up to 28 meters (all directions), thus allowing substantial savings on point sensors and their maintenance.

Detected gases: Ammonia (NH3) - Nitrogen (N2) - Butane (C4H10) - Ethanol (C2H6O) - Hydrogen (H2) - Methan (CH4) - Propan (C3H8), and all gas under pressure above 2 bar.
