Incus Ultrasonic Gas Leak Detector
rosemount incus
The Incus is an advanced ultrasonic gas leak detection system utilizing four ultra-sensitive acoustic sensors which constantly monitor wide areas for ultrasound generated from the release of pressurized gas.
Ideally suited for monitoring well ventilated outdoor environments, the Incus ultrasonic detector has been engineered to withstand even the most extreme conditions and is unaffected by inclement weather, wind, leak direction, and gas dilution or stratification.
