Level measurement during material handling

Level monitoring in silos is indispensable for ensuring smooth operation of storage systems. When they are overfilled, spillage occurs and material is lost. Removal of spilled material is costly and time consuming, and may only be possible when production has stopped. On the other hand, too little material can also lead to problems. That’s why the levels in storage systems have to be monitored. Either a vibrating level switch, an ultrasonic level sensor or a free-space radar sensor can be used for this purpose, depending on the ambient conditions.
