The Rosemount Incus ultrasonic gas leak detector (formerly branded Net Safety) is an advanced leak detection system utilizing four ultra-sensitive acoustic sensors which constantly monitor wide areas for ultrasound generated from the release of pressurized gas. This advanced gas sensing technology never requires calibration or replacement. Some advantages to this detection technology include: it does not have to wait until a gas concentration has accumulated to potentially dangerous concentrations and it does not require a gas cloud to eventually make physical contact with a sensor.

Ideally suited for monitoring ventilated outdoor applications, the Incus has been engineered to withstand even the most extreme conditions. Performance is not affected by inclement weather, wind direction, leak direction or any potential gas dilution, with an instantaneous response to all gas types.

Simply put, the ultrasonic leak detector only triggers an alarm when inaudible, ultrasound is detected (between 25 and 100 kHz) which is only produced with the release of highly pressurized gas. This makes for extremely reliable and efficient performance by the detection system, as there is no poisoning of sensors, it never requires field calibration, and all background noises are accurately accounted for through time delay settings.
