Electronics of LFV excites the piezo-electric-crystals inside the tuning fork, which makes the fork tines vibrate at their natural resonance frequency in free air.
When fork tines are immersed in liquid, the frequency of fork vibration falls due to the density of liquid.
This change in frequency is detected by the electronic circuit.
Liquid presence is thus detected.
