In industrial and commercial tanking systems, the level of the tanks must be monitored continuously in most cases. The level within the tanks can be checked and controlled by means of various level sensors and level gauges. The filling of tanks and silos can be displayed at various points via various level indicators and can thus be monitored. General level measurement can be carried out in various ways depending on the medium selected, size of tanks and the temperature and density of materials used.

Float switch for level control

Different methods of level detection

Level of different mediums can be determined by differential pressure, hydrostatic sensor, ultrasonic sensor, pneumatic level measurement, float switch or by pressure measurement.
