The application range of radar level gauge

The radar level gauge is an advanced guided wave radar level gauge with a maximum measurement distance of 70m. Compared with ordinary measuring instruments, the antenna of the radar level gauge is further optimized, and the new fast microprocessor can perform higher-speed signal analysis and processing, making the application range of the radar level gauge include process vessels or those prone to crystallization and condensate. Strong dust, solid materials, etc. 1. The application range of granular materials In cement plants, most of the raw materials are granular materials, and some are block materials, such as limestone, raw coal, shale, etc. Semi-finished clinker is also a granular material. When it is stored in a warehouse or warehouse, there are residual corners of the material, but it also has a reflective interface. According to the static angle and surface condition of the material formed by feeding and discharging, it is recommended to use a non-contact radar level gauge, that is, a level gauge with a rod or horn antenna, after determining the effective range. Horn antenna level gauge has stronger echo and higher accuracy (0.2%~1%f.s). 2. Application range of powdered materials Cement plants or grinding stations generally have 4 to 8 cement warehouses, in addition to raw meal homogenization warehouses and fly ash warehouses, all of which are powdery materials. Because the powder surface is extremely loose, microwave reflection is quite difficult, and it is difficult to measure its material level without a radar level gauge. The powdered material can be a non-contact radar level gauge with a horn antenna and a large flange. In fact, it combines the cable as an antenna and a waveguide. After the microwave pulse is sent out from the probe, it propagates along the cable, and when the pulse hits the surface of the material, it will be reflected back, and its measurement range can reach 35m. The small dielectric constant of the tested material is 1.6. In addition, the wear resistance and large tensile force of the cable can meet the test requirements of various powder warehouses in cement plants. At present, many cement plants use cable radar level gauges to measure the material level of cement bins and fly ash bins, and have achieved good results.
