Fluid level control relays

Liquid level sensors


Fluid level control relays (liquid level sensors) are devices that, thanks to probes, protect apartments, houses and offices against flooding. The liquid level control sensors available from F&F use the conductivity of the liquid. They are primarily useful in those parts of buildings that are particularly prone to flooding, such as laundries or utility rooms - where there are water valves or flow pipes.

The presence of a failure (flooding the room with water) is detected by shorting the probe electrodes. Depending on the version, the sensor can trigger an alarm and disconnect the electrical circuits.
