Ultrasonic gas leak detectors complement traditional gas detection methods by listening to the ultrasound emitted from a pressurised release. Detection is not affected by wind direction or gas dilution hence the ability to detect leaks at an early stage can be achieved.

Features

Fast response

Instant On-line airborne leak detection

Encapsulated resonant sensor

Continuous Active Measurement

Suitable for hazardous areas

ATEX proved, intrinsically safe

Direct connection to DCS / PLC / F&G

Fully sealed and glanded construction

Detection Coverage

>60 dB range, no field set-up required

>30m (100 ft) detection range

Application

The GDU may be utilised in a wide range of installations:

Offshore Gas / Oil Platforms

FPSOs

Onshore Gas Receiving Terminals

Underground Gas Storage Facilities

Gas Transmission Networks

Aftercoolers / Fin Fans

LNG regassification plants

Gas fired power stations

Compressor Halls
