6.1 Introduction
Rosemount
™
Magnetic Flowmeters provide device diagnostics that detect and warn of
abnormal situations throughout the life of the meter - from Installation to Maintenance and
Meter Verification. With flowmeter diagnostics enabled, plant availability and throughput
can be improved, and costs through simplified installation, maintenance and troubleshoot-
ing can be reduced.
