1.Product principle of level sensor for water tank
level sensor for water tank is an advanced level sensor for tanks and liquids that accurately measures water levels in large tanks, reservoirs or waterways.Radar level gauges use Frequency Modulated Continuous Wave (FMCW) technology. The antenna emits a high-frequency FM radar signal, and the frequency of the radar signal increases linearly. The emitted radar signal is received by the same antenna after being reflected by the measured medium. At the same time, the frequency difference between the frequency of the transmitted signal and the frequency of the received signal 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. Product features of level sensor for water tank
The antenna is small in size and easy to install; the non-contact radar has no wear and pollution.
Almost unaffected by corrosion and foam; almost unaffected by water vapor, temperature and pressure changes in the atmosphere.
Serious dust environment has little impact on the operation of high-frequency level meters.
The wavelength is shorter and reflects better on tilted solid surfaces.
The beam angle is small and the energy is concentrated, which enhances the echo capability and helps avoid interference.
The measurement blind area is smaller, and good results can be achieved for small tank measurements.
High signal-to-noise ratio for better performance even under fluctuating conditions.
High frequency, it is the best choice for measuring solids and low dielectric constant media.
