Observer® i Ultrasonic Gas Leak Detector

Observer® i Ultrasonic Gas Leak Detector

Instantly detect pressurized gas leaks with this high-precision, omni-direction acoustic detector utilizing Gassonic® ultrasonic technology. Works even when traditional methods of gas detection are unsuitable or dependent on ventilation. The Observer-i UGLD provides an industry-leading detection range (up to 28 m) reducing the number of detectors required. 

  • Ideal for use in complex, outdoor pipeline systems - unaffected by wind, gas dilution, and direction of gas plume
  • Artificial Neural Network (ANN) technology distinguishes real gas leak noise from background noise, suppressing false alarm sources
  • Does not require in-field training, fully operational after installation
  • Detects gas leaks from 2 BAR (29 psi) pressure for rapid detection of small gas leaks
  • Patented Senssonic™ self-test function ensures full fail-safe operation
  • Trouble-free maintenance and one-person check and calibration

Gas Detection at the Speed of Sound

Using advanced sound processing, the Observer® i discerns between a gas leak noise event and unwanted background noise, matching omnidirectional acoustic readings with data recordings amassed over a decade from both onshore and offshore facilities in the field. In contrast to earlier generations of ultrasonic detectors listening only at frequencies over 25 kHz, the Observer-i monitors down to 12 kHz without picking up unwanted background noise. This lower frequency range significantly increases the detection radius while maintaining a reduction in false alarms.
