There is no moving part.
Most suitable for detecting sand, aggregate, lime, and so on.
A measured substance that contains moisture to some extent is constantly made contact with the electrode. When the resistance between the electrode and the metal tank wall is reduced, the change of the resistance is detected and the output contact is switched. When the measured substance passes over, the output contact is restored to the initial state.
