DIAL LEVEL INDICATOR 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.
