Radar level meter

1.Radar level meter product principle

Radar level meters are non-contact radar level measuring devices for continuous level measurement, also capable of operating under extreme process conditions.The radar level antenna emits narrower microwave pulses and transmits them downwards through the antenna. After contacting the surface of the medium to be tested, the microwave is reflected back and received by the antenna system again. 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 it takes 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 is easy to install; non-contact radar, no wear and pollution.

Almost not affected by corrosion and foam; almost not affected by changes in water vapor, temperature and pressure in the atmosphere.

Severe dust environments have little impact on the high-frequency level gauge operation.

Shorter wavelengths and better reflect on slanted solid surfaces.

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

The measurement blind spot is smaller, and it will also achieve good results for small tank measurements.

High signal-to-noise ratio allows better performance even in fluctuations.

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