Det-Tronics announce the release of FlexSonic Acoustic Gas Detector

The FlexSonic™ Acoustic Detector is designed to identify the unique ultrasonic frequency content of events such as gas leaks. When a pressurised gas leak occurs, the frequency of the sound being generated ranges beyond the audible portion of the spectrum into the ultrasonic region (above 20kHz). The intensity of the sound generated by a gas leak is determined by several aspects including pressure, leak rate, gas viscosity, and distance from the leak source.

Acoustic detection is less vulnerable to environmental factors (such as high winds) that can degrade the ability of traditional sensing technology based on gas concentration to detect the presence of a leak. When combined with line of sight and/or point gas detectors, the additional layer of protection provided by the FlexSonic™ Acoustic Detector offers the ultimate solution for gas leak detection.
