Radar level gauge application in the industry

The application of radar level gauge in the industry has become very popular, but the parameters and selection of the radar level gauge are very important. The radar level gauge is a new type of measuring instrument, which can be applied to many fields, for liquids and particles. And the continuous level measurement of the slurry, the measurement is not affected by the change of the medium, the temperature change, the inert gas and the steam, the dust, the foam, and the like. The radar level gauge has an accuracy of 1mm, a range of 70 meters, a high temperature of 450 degrees, and a high pressure of 40 kilograms. 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. Various types of conductive, non-conductive media, corrosive media, many users used to measure crude oil, slurry, raw coal, pulverized coal, volatile liquids and solid media.
1. In industrial production, radar level gauges are used in many places, such as the steaming carbon chemical section, the white tank, the hot mother liquor barrel, the cold mother liquor barrel, the alkali liquor mitigation conflict tank, the causticizing tank of the brine project section, Alkaline tank, white bucket, coarse brine tank; crystallizer formed in the calcination section, some of these vessels are easy to form crystals, with mixing; some are volatile, corrosive, large, fast, and high temperature; There is foam and moisture in the slurry. Obviously, contact meters are difficult to meet the requirements, and the differential pressure transmitters that were previously considered appropriate have not been successful. After using the DEC radar level gauge, the radar receiving antenna is considered suitable and uses a 6-inch speaker receiving antenna, a beam angle of 23°, and a microwave frequency of 26 GHz. It is somewhat easy to form a crystal medium, which can be considered as appropriate and uses a vapor counter. Blowing. All of these have been successfully applied in production and have achieved good results.
2. Application in the survey of pure soda silo level. Pure soda packaging silo, dust, material level into a cone type, used to have a difference switch, survey error, maintenance office volume, often false alarm. Cable radar has the following advantages: the survey is not affected by the degree of liquid density, the looseness of solid materials, the temperature of the material, the dust during feeding, and the foam of the external appearance of the object; it has self-diagnosis and long-range operation revealing functions. Up to now, all the pure soda silos have been considered to be suitable and use the cable radar level gauge. The operation is stable, the survey is very accurate, and the service can be beautifully produced.
3. In the lime kiln material level, ash silo material level application, the lime mud kiln top material level temperature is high, the venting part can sometimes reach more than 200 degrees, the material part can reach close to 1000 degrees; the gas flow rate is large, the dust particles are large, the liquid concentration Large; the lower material is irregular stone, the material surface is unfair, and it is easy to scatter. For ordinary radars, it is difficult to use this survey background. In response to this situation, the radar is selected. The radar receiving antenna is considered suitable and uses a parabolic receiving antenna. The size of the surface of the receiving plane or object is large and difficult to be distorted; the beam angle is small, only 4 degrees, the concentrated microwave beam is concentrated; the microwave frequency is 26 GHz. The frequency is high, the wave is uneven, and the hole penetration is strong. It can overcome the despicable background of particles and dust, and overcome the scattering problem of the bulk material. In the upper part of the bell mouth, the compressed air is connected to perform the purge, and the other is to prevent the dust accumulation. On the receiving antenna, the parabolic parabola receiving surface, while reducing the background temperature of the instrument, to ensure the appropriate background of the radar level gauge, can extend the life of the instrument.
