Electro Mechanical Level Measuring System

These use the principle of buoyancy. Here a buoyant element floats on the surface of a liquid and changes position as the liquid level varies. Mechanical or magnetic methods are used to communicate the measured liquid level to a remote indicator. Electromechanical level systems measure the level in bins or silos with dusty, fine-grained or coarse-grained bulk solids in tanks by using a sensing weight.
