Multi-spectral ultrasonic gas leak detector

摘要: An ultrasonic gas leak detector is configured to discriminate the ultrasound generated by a pressurized into atmosphere from false alarm ultrasound. exemplary embodiment includes multiple acoustic sensors for detecting energy and providing sensor signals, including broadband at least one narrowband sensor, an electronic controller responsive signals. In embodiment, provide threshold comparator function compare signal value representative of sensed detection value, Artificial Neural Network (ANN) processing signals derived multitude applying ANN coefficients sources leaks. output generates outputs in dependence on output.
