For E+H electromagnetic flowmeters, if the power supply board fails continuously on the same unit, what could be the possible causes?
Remove the excitation coil wires and electrode wires, and check the insulation level one by one; there may be a problem with the excitation coil, and of course circuit board faults also need to be checked
Newcomers, come and take a look; learn*learn*

Reflecting on the hardships and joys, it is clear that moral decay leads to the downfall of a nation; fraud and inferior quality are the roots of such problems. A hundred years ago, the elders in your hometown already knew this. It’s such a great thing – how could one make mistakes and suffer two defeats? Do only the villains keep failing? Otherwise, where is the axiom, right? :lol
Is the power supply for the electromagnetic flowmeter in question supplied by the DCS system, or is it connected to an external power source?
I hope some expert can explain electronic device knowledge to me
Is it 220V AC output by the UPS? If it is just a regular power supply, take voltage instability into account.
Check if there is a problem with the power supply; it could be a short circuit or damage in the wiring that allows large currents to flow in
