Fluctuations in the Coriolis flow meter in Cologne – seeking solutions
Thread Content
The process medium is coal slurry, with a flow rate of around 35 cubic meters per hour. There are six electromagnetic flowmeters in total across the two systems, and all of them start to fluctuate at the same time. A similar situation occurred before, and it was resolved after changing the type of coal used for pulping; this time, the fluctuation also happened coincidentally due to a change in the coal used for pulping. I seek help from experts in instrumentation – what is the reason?
Well, that’s possible. Is it because of the frequent changes in conductivity through the electromagnetic flowmeter?
1. Perhaps this batch of coal contains a relatively high amount of metallic impurities. 2. Maybe the grindability index of this batch of coal is low, resulting in issues with the quality of the coal slurry; this leads to an increase in small metal particles generated by the wear of steel rods. Ultimately, it’s the reason mentioned on the 2nd floor that is the primary suspect
The conductivity changes frequently; only then does the flow rate change
