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 aggressive liquids, like acids, alkaloids and a wide range of chemical products or hydrocarbons are used. 


When the level of the liquid reaches the level of the float switch, the float changes its position an angle, the ball inside its deviated 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. 


Approximate measures are given in mm.
