Contact radar level gauge

1. Product principle

The high-frequency microwave pulse emitted by the guided wave radar propagates along the detection component (steel cable or steel rod), encounters the measured medium, 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 transmitted pulse and the reflected pulse is proportional to the distance of the measured medium.

3. Product Features

The antenna is small in size and easy to install; non-contact radar, no wear and pollution.

Almost unaffected by corrosion and foam; almost unaffected by changes in water vapor, temperature and pressure in the atmosphere.

Severe dusty environment has little effect on the work of high frequency level meter.

Shorter wavelengths provide better reflection from inclined solid surfaces.

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

The measurement blind area is smaller, and it will also achieve good results for the measurement of small tanks.

High signal-to-noise ratio for better performance even in fluctuating conditions.

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