Process improvements to increase yield or cut manufacturing cost typically require enhanced process control, but the installed base of measurement instrumentation on a process plant may simply be unable to facilitate it, because of age, inadequate performance or unreliability. Maintenance cost and unscheduled process down time for an aging process plant can be very damaging to the balance sheet.
This paper discusses the advances in two-wire instrumentation that make it possible to use flowmeters in hazardous areas, replace old, obsolete instrumentation with more accurate devices, and reduce maintenance and operating costs.
