Abstract: A magnetic flowmeter includes flowmeter electronics and a flowtube configured to receive process fluid flow. The flowtube has a plurality of electrodes disposed proximate an inner diameter to contact process fluid. At least one ultrasonic transducer is disposed within the flowtube and is configured to couple ultrasonic energy to the process fluid proximate at least one electrode. Flowmeter electronics are coupled to the plurality of electrodes and the at least one ultrasonic transducer and are configured to detect at least partial electrode coating or buildup and responsively generate a cleaning cycle within the flowtube using the at least one ultrasonic transducer.
