RF admittance level transmitter is continuous level measurement products based onthe principle of radio frequency admittance, and is developed on the basis of the tradi-tional capacitance level transmitter.

It is widely used for the continuous measurement in the field of petroleum, chemical industry, metallurgy, medicine, electricity, food, paper and other liquid particles.

And it is suitable for the measurement under high temperature, strong corrosion in narrow space environment.

Radio frequency admittance measurement technology is detecting the change of radio waves through the radio frequency circuit.

When the material level meter sensor is installed inside the container, it forms a capacitance apparatus.

The probe is considered as a plate of capacitor, and the container tank wall is considered as another plate capacitor (container as the insulation material) by measuring changes of capacitance value between two plates due to the change of level, RF admittance level transmitter can measure the material level.

RF admittance level transmitter has high stability, high sensitivity, wide applicable field, simple calibration, no need for maintenance, and is suitable for both liquid and solid material.

The instrument body must be reliable grounding and installed steadily to avoid RF rod or cable shaking.
