RF Unique Level Measurement Technology Level Meter
RF Admittance Level Meter Working Principle
RF admittance level meter is a continuous level measurement product based on RF admittance principle. The product has the advantages of high stability, high sensitivity and wide application. Compared with the traditional capacitive level meter, the modular design can be used to set the instrument simply and conveniently. Once the setting is completed, it can be used normally and free of maintenance for life. It enables users to intuitively understand the operation of the equipment and timely deal with problems. It is also safe and reliable in complex industrial occasions.
Radio frequency conductivity measurement technology is a liquid level measurement technology with unique advantages. Although this concept is very similar to general capacitance measurement technology, RF conduction technology adds drive shield circuit and chopper circuit to electronic unit, thus allowing independent measurement of impedance and capacitance resistance. The physical law calculates that the impedance of any suspension is equal to the capacitance resistance of any suspension, so the influence of suspension can be measured by the phase shift of the oscillating circuit and eliminated from the total output.
The probe of the radio frequency conductivity meter is installed in the storage tank, and the radio frequency signal caused by the potential change is obtained through the probe. The probe drive cover can prevent RF current from turning to form a loop through the suspended material, thus ensuring the accuracy of the instrument measurement.
