Electromechanical

Continuous level measurement in bulk solids and bulk solid interface in liquids.  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.  Electromechanical level transmitters are often used in applications with cereals, plastic granulates and powders.  A weight is lowered on a measuring tape.  As it meets the surface of the bulk solids, the tensile force of the weight is reduced.  This change is recognized, the instrument reverses the sense of rotation of the motor and rewinds the tape.  A pulse generator counts the rotations in a non-contact manner as the weight is lowered.  Each counted pulse corresponds to an exactly defined distance.  If this distance is deducted from the overall distance (height of the vessel), the level results.
