    The NivoBob®  NB 3400 electromechanical plumb bob sensor is used for continuous level measurement of separating layers in various tanks and settling basins. It can be used for applications with solids in liquids and does not need to be calibrated. In practice, the simple electromechanical measuring principle makes the NB 3400 the optimal sensor for these applications.
