Corrosion-resistant radar level gauge

1. Product principle

The radar level antenna emits narrow microwave pulses which are transmitted downwards through the antenna. After the microwave touches 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 to be automatically converted into a level signal (because the microwave propagation speed is extremely fast, the electromagnetic wave reaches the target and returns to the receiver after reflection). The time taken is almost instantaneous).

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.
