Guided wave radar level meter

1.Guided wave radar level meter product principle

Guided wave radar level meter Guided wave radar for level measurement of liquids and bulk solids and has good performance in harsh environments.The high-frequency microwave pulses emitted by the guided wave radar propagate along the detection component (steel cable or steel rod). When encountering the medium to be tested, it causes reflection due to a sudden change in the dielectric constant, and part of the pulse energy is reflected back. The time interval between the emitted pulse and the reflected pulse is proportional to the distance of the medium to be tested.

3. Guided wave 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.
