The level meters in rotation are suitable for measurements of states of solids level.
The rotary level indicator is an instrument of robust construction and safe custody, particularly suitable for harsh working conditions and rhythms continued.
The detection is achieved by controlling the rotation of a propeller, positioned inside the tank, driven by a synchronous motor.
In the absence of material, the propeller rotates.
The presence of material around the propeller hampers its rotation causing the switching of the working contact.

A second contact switches off the supply voltage of the motor.
When the level of the product falls, the propeller is free and the motor, powered again, puts the propeller in motion.
The rotary level indicator must be applied on the outer wall of the tank, laterally or from above.
