Radar level gauges fail frequently
Thread Content
The plant is equipped with Guoda radar level gauges. Recently, there have been frequent instances where the measurement values dropped suddenly for 20 seconds before returning to normal levels. I would like to ask what could be causing this issue; the wiring has been checked and there are no signs of loose connections
Since it is on the tank, vibration and electromagnetic interference are not considered. High and low temperatures, as well as insulation, can be taken into consideration. Is the dielectric constant of a medium related to medium waves? Considering production factors, check whether each fluctuation is affected by factors such as feedstock supply. Since you can reply, it shouldn’t be that reason. Is it the director’s radar? If so, could we consider the issue of the director cable? I’ve used the old one once. I don’t know much about it. Check if there is signal filtering.
It is necessary to check the echo curve in a timely manner for inspection. It’s useless to only look at the signal trend.
