What Is The Working Principle Of The Microwave Frequency Of The Radar Level Gauge?

The radar level gauge mainly works through microwave frequency, so what is the working principle of microwave frequency? For the working principle of the radar level gauge, I believe everyone has some understanding. It calculates the measurement results based on the microwave signal, and its microwave signal is inseparable from the microwave frequency. It is mainly divided into C-band, X Band, K-band three frequency bands. Let's give a brief introduction below.
First of all, different microwave frequencies have different waves emitted by the antenna. Generally speaking, the microwave frequency of the conical horn antenna we use is relatively high, its beam concentration is also relatively good, and the beam angle is small, which is very important for the actual use of radar level gauges.
Secondly, the beam of the low-frequency radar level gauge is relatively wide, so if there is a slight ambiguity during installation, it will receive a lot of false echoes inside.
In addition, the frequency of the K-band is currently the highest in the market (26G high-frequency radar level gauge), which will be suitable for more occasions.
Technical advantages of radar level gauges: Radar level gauges measure the continuous level of liquids, particles, and slurries, and the measurement is not affected by medium changes, temperature changes, inert gases, steam, dust, foam, etc. The accuracy of the radar level gauge is 1MM, the range is 70 meters, and it can withstand high temperature of 450 degrees and high pressure of 40 kg. The radar level gauge is suitable for acid-base storage tanks, slurry storage tanks, solid particles, and small oil storage tanks in explosion-hazardous areas. All kinds of conductive, non-conductive media, corrosive media. Such as coal bunkers, ash bins, oil tanks, acid tanks, etc.
