1.Product Principle of High Accuracy Radar Level Sensor
The radar level meter uses frequency modulated continuous wave (FMCW) technology. The antenna transmits a high-frequency frequency modulated radar signal, and the frequency of the radar signal increases linearly. The transmitted radar signal is reflected by the measured medium and received by the same antenna. At the same time, the frequency difference between the transmitted signal frequency and the received signal frequency is proportional to the measured distance. The collected frequency difference signal is subjected to fast Fourier transform (FFT) to obtain the spectrum of the reflected echo, and the distance of the target to be measured is calculated based on this.

3. High Accuracy Radar Level Sensor Product Features
The antenna is small in size and easy to install; it is a non-contact radar, without wear and pollution.
Almost unaffected by corrosion and foam; almost unaffected by water vapor, temperature and pressure changes in the atmosphere.
Severe dust environment has little effect on the operation of high-frequency level meters.
The shorter the wavelength, the better the reflection from inclined solid surfaces.
The small beam angle and concentrated energy enhance the echo capability while helping to avoid interference.
The measurement blind area is smaller, and good results can be achieved even for small tank measurements.
High signal-to-noise ratio for better performance even under fluctuating conditions.
High frequency, the best choice for measuring solids and low dielectric constant media.
