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, wells and containers in which scaling non-clean or residual waters are used, with or without foam in its surface. 


When the level of the liquid reaches the level of the float switch, the float changes its position an angle, the counterweight inside its deviated and activates a micro switch due to this deviation.
When the level of the liquid overreaches the level of the float switch, the float remains in its position in the water due to the counterweight, makes a strenght to the cable that allow the installation of more floats without rolling their cables and reduces the waste’s adhesion.

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. 


Approximate measures are given in mm.
