How to deal with fluctuations in the radar level gauge

Radar level gauge, the effect is very good when it is first used. The measurement is accurate. It has been used for almost a year. It suddenly finds that the output current is high and low and unstable. What caused this? That depends on the extent to which the radar level gauge is high and low. In fact, think about it, nothing more than two situations.
1 First look at this output value, whether it is a regular fluctuation. Whether the output and the local display are consistent. If there is an inconsistency
2 Normally, the liquid level is also fluctuating. It is impossible for any guided wave radar to display the liquid level at a constant level. You can add a little damping time.
Technical advantages of radar level gauge: Radar level gauge measures the continuous level of liquid, particle and slurry. The measurement is not affected by medium change, temperature change, inert gas and steam, dust, foam and so on. 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. All kinds of conductive, non-conductive media, corrosive media. Such as coal bunkers, ash silos, oil tanks, acid tanks, etc.
