Floodline Pipe Sensor (Double Containment)

Basics
Pipe-in-Pipe, or double containment, systems are used in critical areas where it is essential, should the primary inner pipe be damaged or leak, that the contents are safely contained and prevented from escaping into the immediate surroundings.

Operation
The Floodline Pipe Sensor is based around a Point Sensor but designed for fitting into a female threaded socket provided at strategic points in the outer pipe.

Short stainless steel probes extend into the cavity, or annulus, created between the inner and outer pipes. When liquid escapes into the cavity and contacts a sensor the alarm is activated.
The device is equally effective as a “tell-tale” in an overflow pipe. Two types of device are available for water and oil (oil/any liquid).
