NYSP-M22 RF High Sensitivity Wide Range Applications Level Meter
NYSP-M22 RF Admittance Level Meter Working Principle
RF admittance liquid level meter is a continuous liquid level
measurement product based on RF admittance principle. The product
has the advantages of high stability, high sensitivity and wide
application range. Compared with the traditional capacitance liquid
level meter, the modular design can make the instrument setup
simple and convenient. After setting, it can be used normally and
maintenance free for life. It enables users to intuitively
understand the operation of equipment and deal with problems in a
timely manner. 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 the 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
capacitive 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
potential change is obtained through the probe. The probe drive
cover can prevent the RF current from forming a loop through the
suspended material, thus ensuring the accuracy of the instrument
measurement.
