How To Deal With The Up And Down Fluctuations Of The Radar Level Gauge?

The radar level gauge, when it was first used, it worked very well, and the measurement was accurate. After using it for almost a year, I suddenly found that the output current was fluctuating and unstable. What is the reason for this? , It depends on the extent to which the radar level gauge fluctuates up and down. In fact, if you think about it carefully, there are only two situations.
1. First look at the output value, whether it is a regular fluctuation. Whether the output is consistent with the in-place display. If not, there is a problem with the table.
2. Under normal circumstances, the liquid level is also fluctuating. It is impossible for guided wave radar to display the liquid level at one point. You can increase the damping time a little.
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. Conductive, non-conductive media, corrosive media. Such as coal bunkers, ash bins, oil tanks, acid tanks, etc.
