Background

The radio frequency admittance level meter is a general level meter used for measuring continuous level, and the radio frequency admittance is a novel level control technology which is developed from capacitance, prevents hanging of materials, is more reliable and accurate, and has wider applicability, and is the upgrade of the capacitance level technology. By admittance, the meaning of admittance is the inverse of the impedance in the electrical system, which is a combination of resistive, capacitive and inductive components, whereas radio frequency, i.e. the high frequency radio spectrum, is understood to mean that the admittance is measured by high frequency radio waves. When the instrument works, the sensor of the instrument, the filling wall and the measured medium form an admittance value, when the material level changes, the admittance value changes correspondingly, and the circuit unit converts the measured admittance value into a material level signal to be output, so that the material level measurement is realized.

However, in practical applications, the conventional apparatus may work under various conditions, for example, in a narrow pipeline, and the probe may have insufficient length, so that an operator needs to process the pipeline to enable the probe to go deep into the pipeline, which increases difficulty of operation.
