[0002] The continuous RF admittance level meter is an instrument for continuous measurement. It consists of a circuit unit and a rod or cable sensor element, and is suitable for measuring conductive liquids and insulating liquids. RF admittance level control technology is developed from capacitive level control technology. It has the characteristics of anti-hanging, more reliable, more accurate, and wider applicability. The working principle of the instrument is based on the reflection and propagation delay of RF signals. When working, the continuous RF admittance level meter emits a beam of RF signal, which is reflected by the surface of the material in the material bin. According to the intensity and propagation delay of the reflected signal, the position of the material in the material bin can be calculated. Specifically, when the material is piled high, the intensity of the reflected signal will be weaker and the propagation delay will increase; when the material is piled low, the intensity of the reflected signal will be stronger and the propagation delay will decrease. The continuous RF admittance level meter is an efficient and reliable material detection tool that can meet the measurement needs of various material bins.
