Why is the traffic unstable?
Thread Content
When our company produces ordinary products, the flow meter for liquid caustic shows a stable flow rate, but when producing another type of product, the flow rate becomes unstable. What exactly is going on?
Please specify what type of flow meter it is
Mass flow meter, seems to be from ROSEMOUNT
It has nothing to do with the flow meter, right? Is it automatically adjusted?
Based on what you’ve described, there should be no issue with the flow meter; it’s likely a problem related to the process itself. It is recommended to look for the reasons mainly from a process perspective.
Are there any issues such as fluctuations in the process operation or the presence of air?
You state that the media for your two products are different; therefore, the flow meters you use may not be suitable
The medium hasn’t changed; it’s just the amount added that has changed
The traffic has changed. There is a problem with the process control; the flow meter is fine (except that its measurement range is out of spec)
There is a problem with the process control; how can this be explained? We simply reduced the flow rate – the process itself hasn’t changed
Is it because the flow rate is too low, or isn’t the pipeline fully filled? When the flow rate is high, this issue isn’t as apparent
The difference in traffic before and after is a bit over 100, which isn’t that much. But what was said above is also quite possible; it’s worth looking into
