Control of liquids

Float levels switch


Intended use:

The floats are to be used to control the level in the filling and emptying processes of tanks and containers in which non-scaling clean or residual waters are used. They are specially designed to be introduced through little holes.

There is, under request, a mounting accesory made of PVC and with a G 1 “ thread that fixes the float and allows the adjustment of the level due to a cable gland. 


When the level of the liquid reaches the level of the float switch, the float changes its position an angle and activates a micro switch due to this deviation.
It is necessary to install 2 devices to control of the maximum and the minimum levels automatically. 

Mechanical connection:

It is simple: the switch literally hangs on its own cable at the desired height and is fixed to the ceiling or to one side of the tank adjusting the distance of the counterweight, if it was requested. 


Approximate measures are given in mm.
