Ultrasonic Gas Leak Detector
The Gassonic Observer-H Ultrasonic Gas Leak Detector from General Monitors is ideal for gas leak detection in pressurized systems. The new Gassonic Observer-H features HART communications, Modbus with single and block transfer modes, Emerson AMS Intelligent Device Manager support, and event logging. The Observer-H is ATEX, IECEx, FM and CSA hazardous area certified and SIL 3 suitable. It detects gas leaks by sensing the airborne ultrasound emitted from leaking gas at high pressure. Since the gas leak detector responds to the source of a gas release rather than the dispersed gas, it is unaffected by changing wind directions, gas dilution, and the direction of the leak. The Gassonic Observer-H’s wide coverage zone makes it possible to supervise areas up to a 20 meter radius, for the detection of leaks as small as 0.1 kg/sec., with only one device.
