Dial level indicator
The dial level indicator has been designed for the level measurement
of liquids in small and high tanks. Its operation is based on a clock gears
movement of highest precision that assure a local indication with high
accuracy and repeatability. Two mechanisms have been planned in order
to have two reading scale with single or double pointer.
The instruments doesn't need any electrical supply. The main characteristics are the reliability and the strength.
