Questions about electromagnetic flowmeters
Thread Content
There is an electromagnetic flowmeter installed on the sewage pipe. The pH of the sewage is around 10, and the electromagnetic flowmeter has suffered severe scaling, making it difficult to clean. Is it possible to soak it in dilute sulfuric acid? The electrode material is 316L stainless steel, while the lining is PTFE. It needs to remain in operation during this process. Thank you everyone
The body material is usually carbon steel; it cannot be soaked or washed online
10% dilute sulfuric acid was used, and not even a brush could remove it
You need to first determine what type of scaling is present in order to take targeted action; if this situation persists, it is recommended to use a non-electrode capacitive electromagnetic flowmeter
Waiting online is pointless; there are so many chemical cleaning companies out there. You can get quotes just by posting a request, so why would they bother sending money?
Dilute sulfuric acid can also corrode the electrodes of 316L. Following your approach, try not to soak it; brushing is fine, and just rinse it thoroughly with clean water after brushing.
