Precautions for Guided Wave Radar Level Meter in Powder Media Measurement

Only after fully understanding the characteristics of the material and on-site application conditions, can the right product be selected correctly. The following are the precautions for the installation of the guided wave radar level meter for measuring powder. 1. When the guided wave radar level meter measures the dust raised by the medium, it will stick to the bell mouth and affect the measurement accuracy. It needs to be purged frequently to ensure the accuracy of the accuracy to a certain extent. Users should take this into consideration when purchasing to avoid problems in subsequent use. 2. The antenna selection of the guided wave radar level meter must be equipped with the height of the riser, and the lower part of the antenna must be below the end of the nozzle, extending into the container at least 10mm, effectively eliminating the interference from the nozzle. 3. Center installation is no problem for short-circuit large-diameter containers, but there are problems for narrow and high containers. When mounted in the top middle of a flat-topped vessel, a guided wave radar level gauge will also receive an echo and an indirect echo that may return from the sidewall path, depending on height and diameter. 4. Due to the interference of blanking dust, avoid installing the guided wave radar level gauge too close to the feeding port of the material, nor can it be installed between the feeding port and the dust collection port. The installation position should follow the principle of 10:1, and the sensor needs to be installed at a position one tenth of the tank (silo) height from the tank (silo) wall. Example: If the tank (silo) is 10 meters high, the radar instrument should be installed 1m away from the container wall. 5. Avoid installing the guided wave radar level gauge too close to the tank (silo wall), then the best choice is the position of 1/3 to 1/4 of the diameter of any tank (silo) (away from the pipe wall). ). The minimum inner diameter of the nozzle is 50mm (2”), and the optimal diameter is 150mm (6”) or larger. When installing the manhole, the most off-center installation principle must be followed. Because risers, threaded nozzles or manhole covers are often found at this point, nozzle sizes vary widely, with a large diameter and small height nozzle being better than a tall, small straight nozzle. 6. Avoid installing in the center of the top of the hemispherical or parabolic container. Because in this case, the energy collected from multiple reflections back to the antenna may exceed the energy reflected directly from the surface of the medium. When the guided wave radar level gauge is installed at the center of the top, in addition to generating indirect echoes, it will also be affected by multiple echoes, and the multiple echoes may be larger than the secondary value of the real echo, because the top can Aggregate multiple echoes. The solution is to use the first wave algorithm and reduce the set value of the echo threshold curve. When the level of the container decreases, you will see two very close peaks in the echo graph. When this happens, the guided wave radar level gauge cannot accurately and stably identify the position of the echo, and the level reading can also fluctuate when the level changes. The set value of the wave threshold curve or change the installation position of the instrument.
