Simple pneumatic tank contents gauge with easy to read dial face.
The gauge can be sited within 50 metres of the tank. A thin tube connects it to a sensor in the base of the tank. By pumping the tube full of air, the gauge indicates the weight of water pressing on the sensor.
Once the unit is calibrated, the dial then indicates the fullness of the tank in percentage terms.
Two models are available; the manual version with hand primer, or the electric version with button operated pump.
