The rotary level indicator PFG57 compact, thanks to its small size, is ideal for mounting on small tanks or cells dosing.
It is a measuring device for powdery or granular solid suitable to detect only level states, for example: minimum, medium and maximum.
Its operation is based on the continuous rotation of the propeller which, after meeting the resistance of the material, hangs by actuating a microswitch signaling the presence of the material.

The gauge PFG57 can be supplied with extension of lenght, with or without protection, determined by the buyer when ordering.


  • No need for calibration
