ABSTRACT:
A magnetic flowmeter is disclosed that includes a pair of electrodes coupled to a process fluid and a diagnostic circuit coupled to the pair of electrodes to monitor a common mode signal. The diagnostic circuit is adapted to detect a poor ground connection associated with at least one electrode of the pair of electrodes based on line noise associated with the common mode signal.
