Fundamental Principles The tuning fork of small type is a kind of universal position sensor, which is brought to its resonance frequency by means of piezoelectric crystals drive. If the tuning fork covered by liquid or solidity, this frequency will change. The electronics of the small tuning fork monitor the resonance frequency and then output a switching value, in this way, to alarm and control the liquid level.
