1. Working Principle

The electric circuit signal energizes the crystal in the fork which makes the probe of the tuning for vibrate at a certain rate. When the probe is completely whelmed by the material measured, the vibration frequency of the fork will be changed, then the electric circuit of the meter can automatically detect the difference and transfer it into switch signal which will be output by the relay for on-spot alarming and remote control; when the material departs from the probe, the meter restores to the normal working condition to detect the changes of material level.



2. Installation Method

Vertical or horizontal installation



3. Product Features

a. complete electrical design circuit, without maintenance after operation

b. without effect of foam and powder

c. special tuning fork design and its inherent vibration characteristic which ensure the function of automatic elimination and maximally prevent material hanging



4. Applications

Liquids, solids, particles and powder with good fluidity in various fields.
