Guided wave radar level meter

1.Product Principle of Guided wave radar level meter

The high-frequency microwave pulses emitted by the guided wave radar propagate along the detection components (steel cables or steel rods) and encounter the measured medium. Due to the sudden change in the dielectric constant, reflection occurs and part of the pulse energy is reflected back. The time interval between the transmitted pulse and the reflected pulse is proportional to the distance of the measured medium.

3. Guided wave 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.
