The level indicator provides a precise and independent indication of the level of your cistern, as a percentage of the fill level, regardless of the tank shape. This pneumatic gauge is suitable for remote measurement up to a distance of 50 metres.
The impact-resistant plastic housing ensures a robust and durable construction. The level indicator is supplied with a 20 m measuring line and matching mounting parts so that you can easily install it on your tank. The measuring accuracy is +/- 3% of full scale, thanks to the linear capsule spring that ensures precise measurements.
Pneumatic measuring process
Measurement of the hydrostatic ground pressure depending on the filling level of the cistern.
2 years warranty
We offer a WISY guarantee of 2 years for our pneumatic level indicator.
During the pneumatic measurement of the fill level, the hydrostatic ground pressure is measured, which varies depending on the fill level of the cistern. The pressure is usually taken 5 cm above the tank bottom and converted into the fill level on the dial. The dial shows the filling level in %.
Pneumatic pressure is built up in the measuring line system by means of an integrated pump until it is equal to the water pressure above the tank bottom. The pointer has now reached the highest level, the pressure generated by the pump has displaced the liquid column in the measuring line. The air now escapes bubbling out of the measuring line end at the bottom of the tank and the pointer remains in the measuring position . Semi-permanent indication, i.e. the pump closes the measuring line system at top dead centre, the pointer stops temporarily and then drops again very slowly.
