Detected fluid
for industry


The Surveyor detects gas leaks by sensing the airborne ultrasound emitted from leaking gas at high pressure. Ultrasonic gas detection is based on robust and proven Gassonic technology and designed for long and failsafe operation in extreme environmental conditions. Because the Surveyor 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 gas leak. •Advanced stainless steel microphone provides instant detection of high pressure gas leaks with coverage up to 20 meters in radius •4-20 mA output for remote alarm and fault indication •One-person sound check and calibration for high reliability and trouble free maintenance •Intrinsically safe, EExi design integrates cable termination. No extra junction box needed •LED display provides visual indication for various detector functionalities Markets: General Industry, Oil & Gas, Utilities Applications • Offshore and Onshore Oil and Gas Installations Floating Production Storage and Offloading Vessels (FPSOs) • Gas Compressor and Metering Stations • Underground Gas Storage Facilities • Petrochemical Processing Plants • Hydrogen Storage Facilities • LNG/GTL Trains • LNG Re-gasification Plants • Gas Turbine Power Plants • Refineries Features & Benefits • Advanced stainless steel microphone permits instant detection of high-pressure gas leaks with coverage up to 20 meters in radius • Interface outputs include 4–20 mA analogue and alarm/fault relays according to industry standards • Full AISI 316L stainless steel intrinsically safe housing enclosure provides corrosion resistance in harsh environments
