Analysis of common fault causes when electromagnetic flowmeter measures sewage

The daily maintenance and upkeep of electromagnetic flowmeter is actually very simple. However, when the electromagnetic flowmeter measures the sewage flow, the measured medium often adheres to or scales on the inner wall of the electrode and the measuring tube. The inner wall of the measuring tube and the electrode must be cleaned regularly. Be careful not to damage the lining and electrode of the flowmeter. So when the electromagnetic flowmeter has problems in measuring sewage flow, where should we start? Today, the author will solve this doubt for everyone.

First, we need to check whether the medium in the measuring tube is full, whether there is scaling on the lining of the flowmeter and the electrode of the flowmeter, and whether all the cable connections of the flowmeter are reliable. Then, we need to check whether there is leakage in the pipe system where the flowmeter is installed, whether the upstream and downstream valves will have any impact, whether the installation position of the flowmeter is suitable, and whether the grounding requirements of the flowmeter meet the requirements. It is best for us to check whether the excitation coil of the flowmeter is short-circuited or open-circuited, whether it is insulated from the ground, and whether the surrounding environment interferes with the flowmeter. After we check the above reasons, we can respond quickly and solve the fault as soon as possible. If the above situation is not the cause of the fault, then we can detect whether the converter of the electromagnetic flowmeter has failed. I hope it can help all readers.
