Smart Radar Level Gauge

1. Product Principle of Smart Radar Level Gauge

Smart radar level gauge is also called high-precision radar level gauge. The smart radar level gauge uses microwaves to have good penetration and strong adaptability to harsh environments and measured materials. The antenna is further optimized. The new fast micro The processor can perform signal analysis and processing at a higher rate. The radar level gauge adopts 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 transmitted radar signal is received by the same antenna after being reflected by the measured medium. 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 to the target to be measured is calculated based on this.

3. Product Features of Smart Radar Level Gauge

The antenna is small in size and easy to install; non-contact radar, no wear and pollution.

Almost unaffected by corrosion and foam; almost unaffected by changes in water vapor, temperature and pressure in the atmosphere.

Severe dusty environment has little effect on the work of high frequency level meter.

Shorter wavelengths provide better reflection from inclined solid surfaces.

The beam angle is small and the energy is concentrated, which enhances the echo capability and helps avoid interference objects.

The measurement blind area is smaller, and it will also achieve good results for the measurement of small tanks.

High signal-to-noise ratio for better performance even in fluctuating conditions.

High frequency, the best choice for measuring solid and low dielectric constant media.
