Instrument Tag

on . Posted in Instrumentation & Controls Engineering

Typically instrument abbreviations consist of two parts. The first letter indicates the process.  The second letter or two letters indicates the function.  Sometimes a third letter is used to indicates additional measured variables.  These letters identify the instrumentation process and are displayed in a instrument bubble consisting of two parts.  The top half of the bubble represents the process and the bottom half the tag number.
