Radar level antennas emit narrower microwave pulses that are transmitted downward through the antenna. After the microwave touches the surface of the measured medium, it is reflected back and received again by the antenna system. The signal is transmitted to the electronic circuit and is automatically converted into a level signal. The time taken is almost instantaneous).
r level gauge features
♦The antenna size is small for easy installation; non-contact radar, no wear and no pollution.
♦Hardly affected by corrosion and foam; hardly affected by water vapor, temperature and pressure changes in the atmosphere.
♦The severe dust environment has little effect on the operation of the high-frequency level gauge.
♦Shorter wavelengths give better reflection on inclined solid surfaces.
♦The beam angle is small and the energy is concentrated, which enhances the echo capability and helps avoid interference.
♦The measurement blind area is smaller, and it can also achieve good results for small tank measurement.
♦High signal-to-noise ratio for better performance even in fluctuations.
♦High frequency is the best choice for measuring solid and low dielectric constant media.
