The IO output of the Cologne flowmeter converter was damaged as a result of welding in the pipeline; the current level remained above 20 milliamps. Has anyone encountered this issue? Did you manage to identify which component was damaged and fix it?

It was damaged by welding; the output is 0 mA. Fortunately, the gauge still shows normal readings, but it cannot be repaired since it won’t turn on.

Is the IO board broken? Try to find a good one of the same model of IO board

There are no spare parts left; those used for replacement later on are all from Yokogawa

Oh, if there’s a chance to take it apart and check which component on the IO board is damaged, let me know. I don’t have any spare parts to replace it; for now, only the gauge head is visible. In the future, I’ll replace it with a Yokogawa one
