This high-precision all-round acoustic detector uses Gassonic ultrasonic technology to instantly detect pressurized gas leaks. Even when traditional gas detection methods are not applicable or rely on ventilation, this detector can still work. The artificial neural network (ANN) technology it uses can distinguish true gas leaks from false alarm sources without any on-site training. Observer i UGLD provides industry-leading detection range (up to 28 meters) and reduces the number of required detectors. It is highly suitable for complex outdoor piping systems.
