The working principle of tuning fork level sensor is based on vibrating a tuning fork sensor continuously at its natural frequency and detecting the change of frequency and amplitude in the presence of application media. The monitoring process of given parameters depends upon type of application media.
A specially shaped tuning fork is kept vibrating using piezo-electric elements. The oscillation of the tuning fork damps when in contact with the material. The loss of oscillation amplitude is detected and used for switching a relay. The output contacts of the relay are in turn used for annunciation and/or control.

The vibrating fork type level switch working principle is indeed simple, effective, reliable and cost-effective means to measure or detect the presence and absence of liquids and bulk solids.
How does a vibrating fork level switch work?
The vibrating fork type level sensor works on the principle of tuning forks. When the fork comes in contact with liquids/solid material, the frequency slightly changes, and this change in frequency is sensed by the electronic circuit which in turn send out a signal.
