Product Details


 RF admittance level meter is a general type continuous level meter which is developed from 

the capacitance level meter technology. The meter consists of a electronic unit, a explosion-proof 

shell and hard or flexible probe elements. The sensors have a variety of materials and structures. 

It is widely applied in the level measurement of many medium under complex condition on the 

basis of specific measurement principle and structure.
