Principle of tuning fork level meter :
The tuning fork level meter works by vibrating the tuning fork at a certain resonant frequency through a pair of piezoelectric ceramics crystals mounted on the tuning fork base. When the tuning fork is in contact with the measuring medium, the frequency and amplitude of the tuning fork will change. These changes are detected by the intelligent circuit, processed and converted into a switching signal.
Advantages of multilayer piezoelectric ceramics in the tuning fork level meter:
Large amplitude of vibration
High reliability, solving the problem of easy damage of ceramic parts of conventional products
