Holding tank sensors


Electronic Field-Effect Sensor

This kind of sensor is able to detect the water level from the outside of the tank.
It can operate on plastic holding tank only.



Pneumatic Sensor

The rising of the water level inside the tank generates pressure which activates the electrical contacts of the pressure switch.
The water level indicator pipe must be installed in the top of the tank, possibly at the centre.
The sensor is immune to false signals caused by the movement of the boat.
For total reliability, the sensor has been designed with no moving mechanical parts inside the tank.
