The number of valves and valve types that go into modern process plants today to precisely control operations is huge. Because of the critical role they can play, the increasing numbers mean a corresponding increased need to monitor how well these valves operate. Yet in too many cases, this does not occur. The lack of information coming from a large proportion of today’s valves can lead to poor performance and inefficient operation. One of the tools at our disposal to achieve effective valve monitoring is wireless technology.
