The Observer® i Ultrasonic Leak Detector is an advanced gas leak detection system that identifies pressurized gas leaks by monitoring the ultrasonic sound generated by escaping gas. Unlike traditional gas detectors that rely on gas concentration reaching the sensor, the Observer® i detects leaks at the speed of sound, enabling rapid response and enhanced protection of personnel, assets, and operations.

Featuring proprietary Artificial Neural Network (ANN) technology, the detector analyzes acoustic signatures in real time to distinguish actual gas leaks from background industrial noise. This intelligent processing significantly reduces false alarms while maintaining high sensitivity, even in complex and noisy environments. The system requires no field training and is fully operational immediately after installation.

The Observer® i provides an industry-leading detection range of up to 28 meters and can detect leaks from pressures as low as 2 bar (29 psi), making it particularly effective for outdoor pipeline systems, gas storage facilities, compressor stations, and hydrogen applications. Because detection is based on sound rather than gas dispersion, performance is not affected by wind direction, ventilation, or gas dilution.

Key features include the patented Senssonic™ self-test function for continuous operational verification, HART® and Modbus® communication capabilities, integrated event logging, and simplified one-person maintenance and calibration procedures. These capabilities help improve system reliability while reducing maintenance effort and lifecycle costs.

With its fast response, wide-area coverage, intelligent acoustic analysis, and robust industrial design, the Observer® i Ultrasonic Leak Detector provides a highly effective solution for early gas leak detection and enhanced safety in critical industrial applications.
