General Monitors’ Gassonic Observer-i Ultrasonic Gas Leak Detector provides ultrasonic gas leak detection with false alarm suppression for floating production storage and offloading vessels, petrochemical refining plants, gas/hydrogen storage facilities, gas compressor stations, LNG/GTL trains and LNG re-gasification plants.
Designed with artificial neural network (ANN) intelligence and real-time broadband acoustic sound processing technology, Gassonic Observer-i Detector makes it possible to fully analyze the sound spectrum down to 12 kHz, the company says. The ANN algorithm has been “trained” to automatically distinguish between unwanted acoustic background noise and gas leaks. The company says this design provides a broader leak detection range, which also increases sensitivity to smaller gas leaks without interference from unwanted background noise.
Ultrasonic gas leak detectors are used in pressurized gas applications to complement conventional gas detection methods. In outdoor or ventilated locations, conventional detectors can miss gas leaks due to wind conditions, gas dilution or leak directionality. To compensate for such situations, ultrasonic gas leak detectors recognize gas leaks by responding to the airborne ultrasound instead of relying on physical contact between the gas and the sensor element. This capability significantly improves total speed of response to dangerous gas leaks.
The Gassonic Observer-i Detector features the patented Senssonic self-test function. This self-test checks the device’s electrical integrity and microphone every 15 minutes and ensures the Gassonic Observer-i Detector is operational at all times. Both the microphone and the microphone windscreen are constantly monitored to ensure that the detector always has optimal sensitivity and detection coverage.
Designed to support large plant distributed control systems, the Gassonic Observer-i Detector features HART and Modbus communication compatibility, along with 4-20 mA output, providing complete status and control capability in the control room. It features ATEX, IECEx, FM, and CSA approvals and is SIL 3 suitable.
