RF Admittance Level Meter Operating Principle

 

Radio-frequency admittance measurement technology is a kind of material level measurement technology with unique advantages. Although the concept of capacitive measurement is similar to that of conventional capacitive measurement technology, RF admittance technology adds Driving-Shield circuit and chopper circuit to the electronic cell, so it can measure impedance and capacitive reactance separately. after passing through the laws of physics, it can be obtained that the impedance and capacitance reactance of any hanging material are equal, so the effect of the hanging material can be measured and the phase shift of the oscillating circuit is passed through, which is eliminated from the total output.
the probe of RF admittance level meter is installed in the storage tank, and the change of RF signal caused by the change of material level is obtained by the probe. the Driving-Shield End of the probe can prevent the RF current from forming a loop through the hanging material, which ensures the accuracy of the instrument measurement.
