Radar level meter

1.Radar level meter product principle

The radar level antenna emits a narrow microwave pulse, which is transmitted downward through the antenna. After the microwave contacts the surface of the measured medium, it is reflected back and received by the antenna system again, and the signal is transmitted to the electronic circuit part and automatically converted into a level signal (because the microwave propagation speed is extremely fast, the time taken for the electromagnetic wave to reach the target and return to the receiver through reflection is almost instantaneous).

3. Radar level meter 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.
