Ultrasonic Gas Leak Detection

Gas Detection Wind

Detect gas leaks at the speed of sound, using Ultrasonic Gas Leak Detection !!!!

Technologies that have traditionally been used in fixed installations to detect hydrocarbon gas leaks, such as Catalytic/IR Point Sensors and IR Open Path Sensors all have one limitation: in order for a leak to be detected, the gas itself must either be in close proximity to the detector or within a pre-defined area.

Unfortunately, outdoor environmental conditions such as changing wind directions and quick dispersion of the gas cloud from a leaking outdoor installation often cause traditional gas detection systems to fail simply because the gas never reaches the detector. 

Traditional gas detection systems need to wait for the gas to form a vapour cloud, which may or may not ignite, and which may or may not allow loss prevention by enabling Shutting down the gas facility in time.

Ultrasonic Gas Leak Detectors (UGLD) respond at the speed of sound at gas leak initiation, unaffected by changing wind directions and dilution of the gas.

Ultrasonic Gas Leak Detection = Instant Gas Leak Detection

Ultrasonic gas leak detectors respond to the ultrasonic noise, which pressurised gas leaks generate. Therefore, they detect leaks instantly in a radius from the detector without having to wait for an explosive gas cloud to build up and without being affected by wind conditions. An essential performance parameter for an Ultrasonic Gas Leak Detector is to ensure high acoustic sensitivity to real gas leaks over a large area, while at the same time minimizing the interference from background noise sources unrelated to gas leaks.

The ultrasonic acoustic gas leak detection technology detects leaks from pressurized gas systems by sensing the airborne ultrasound produced by the escaping gas. This means that the ultrasonic gas leak detectors detect gas leaks at the speed of sound.

Unlike conventional gas detection methods (point or open path gas detection) the ultrasonic gas leak detectors do not have to wait for the gas to accumulate into a potentially dangerous gas cloud and come into physical contact with the detectors. They instantaneously raise an alarm if a leak is detected. The illustration illustrates a flange leak. The ultrasonic acoustic gas leak detector will pick up this leak without being affected by conditions such as changing wind directions, gas dilution, and the direction of the gas leak – conditions relevant for most outdoor gas installations.

Precision Safety Solutions offer two product types for Ultrasonic gas leak detection. the MSA Gassonic i and the Honeywell Searchzone Sonik ultrasonic gas leak detectors.

MSA Gassonic i UGLD


Instantly detect pressurized gas leaks with this high-precision, omni-direction acoustic detector utilizing Gassonic ultrasonic technology. Works even when traditional methods of gas detection are unsuitable or dependent on ventilation. Features Artificial Neural Network (ANN) technology that distinguishes between real gas leaks and false alarm sources without requiring any in-field training. The Observer-i UGLD provides an industry-leading detection range (up to 28 m) reducing the number of detectors required. Ideal for use in complex, outdoor pipeline systems.
