All modules indicate status and alarms via LEDs on the front and alarms via a relay output (option).
Acoustic leak detection
Leak detection without a leakage wire
Sonitus listens to sound and vibration in the steel pipe with sensitive accelerometers. One sensor hears 0–250 m of pipe in both directions, and on a section of two modules the system estimates where the leak is.
