Radar Level Gauge

Радарный уровнемер

  • The principle of the FMCW radar level meter is that the radar emits electromagnetic waves on the tank top, and the electromagnetic waves are received by the radar after being reflected by the medium. The frequency difference δf between the received signal and the transmitted signal is proportional to the distance R to the surface of the medium: R= C (speed) * δf (frequency difference) / 2 / K (frequency modulation slope). Because the speed of light C and the frequency modulation slope K are known, the frequency difference δf can be calculated to obtain the distance R from the radar installation position to the material surface. Then, the known total height of the tank is subtracted from the spatial distance from the radar to the material surface (referred to as the empty height) to obtain the height of the material level.

Характеристики товара

1. The millimeter wave radar has a measurement accuracy of up to ±1mm, and the measurement blind area is 10-50mm.

2. Smaller antenna size to meet more working conditions.

3. Multiple lens antennas, 3° emission angle, more concentrated energy, stronger echo signal, higher reliability than other radar products under the same industrial and mining conditions.

4. It has stronger penetration and can be used normally even in the presence of adhesion and condensation.

5. The dynamic signal range is larger, and the measurement of low dielectric constant media is more stable.

6. Multiple measurement modes, radar response time is less than 1S in fast measurement mode.
