The working principle of tuning fork switch is:

The tuning fork vibrates at a certain resonant frequency through a pair of piezoelectric crystals mounted on the tuning fork base.When the tuning fork level switch is in contact with the measured medium, the frequency and amplitude of the tuning fork will change. These changes of the tuning fork level switch are detected by inligent circuit, processed and converted into a switch signal.

free flowing medium density solid powder and particle, especially good at controlling liquid level of various liquid medium.
