ABSTRACT:
An magnetic flow meter is provided which includes a reference electrode configured to electrically couple process fluid flowing within a flowtube of the flow meter. The reference electrode is adapted to measure potential of the process fluid. A current limiter is configured to limit current flow through the reference electrode and thereby reduce corrosion of the reference electrode.
