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.
