Bluesky tuning fork level switch is caused by the resonance of piezoelectric crystal to cause vibration. When subjected to material damping, the amplitude is drastically reduced and the frequency and phase change significantly. These changes are detected by the internal electronic circuit and processed. , converted into a switch signal output.

Advantages：
The Bluesky tuning fork level switch can monitor, control and alarm the high and low positions of the tank, and is suitable for various liquid, powder and granular solids. It is practical, simple, reliable, and adaptable. It is basically maintenance-free, and the tuning fork and output are working.
All types have high or low fault alarm modes and selectable meter switch sensitivity.
