This is a user manual for the PermAlert system, which can monitor liquid flow in pipes.
This manual provides installation and operating instructions for the PermAlert FluidWatch leak detection monitoring system, covering models FW 25-50, FW 25-75, and FW 25-100. The system consists of a solid-state electronic monitoring unit connected to a sensor cable to detect water and water-based liquids in small areas such as equipment rooms or raised floors.

The manual covers Models FW 25 -50, FW 25 -75 and FW 25 -100 Leak Detection Monitoring Systems.
The system continuously monitors the capacitance of the sensor cable and detects changes from the initial value when it contacts water.
The unit turns on a red LED, switches two relays, and sounds a horn.
Sensitivity is adjusted using two resistors labeled 'Coarse' and 'Fine' to set Low, Medium, or High sensitivity.
