In sulfur acid production plants, what are the reasons why the electromagnetic flow meter for the acid in the second absorption tower drops from 620 to around 520? Thank you

Universal Haiyou: In a sulfur-based acid production plant, what are the reasons why the electromagnetic flow meter for measuring acid flow in the second absorption tower has seen its reading drop from 620 cubic meters to around 520 cubic meters? Thank you
Has only the acidity level decreased? Any other parameters? As the pump frequency is reduced, the acid level decreases. The pump current decreases, the speed drops, and the acid level falls. As the acid tank level drops, the amount of acid decreases. A blockage in the pump inlet causes a decrease in acid level.
It’s very likely to be a gauge issue; you can adjust the gauge and see.
It would be best to upload the dry suction DCS screen; the amount of information available is too limited, so everyone can only guess.
I really want to share it! I just don’t know if this counts as an illegal confidentiality agreement!
