FlexSonic® Acoustic Detector + Transmitter

The FlexSonic® Acoustic Detector – comprised of the AC100 Acoustic Sensor and the ATX10 Acoustic Transmitter (Spec Sheet: 90-1208) is designed to recognize the unique frequency content of events such as gas leaks.

When a pressurized gas leak occurs, the frequency content of the sound being generated extends beyond the audible portion of the spectrum into the ultrasonic region (above 20 kHz). The intensity of the sound generated by a leak is determined by several factors including pressure differential, leak rate, gas viscosity, and distance from the leak source.

Acoustic detection is less susceptible 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.
