Various methods can be used to provide a profile of zone interfaces within a thickener.  Hydrostatic pressure sensors work on theoretical bed level calculation, turbidity sensor indicate overflow clarity, buoyancy based electromechanical systems drop weights into the thickener at rake intervals, ultrasonic sensors use a submerged transducer probe.

Depending on your application and desired objective, we specify the best-suited technology that will improve your process optimization and operation.
