Instrument Abbreviations Used in Instrumentation Diagrams (P&IDs) II Custom Search We have already seen how the letters A – Z are combined in instrumentation diagrams to give process instruments unique function and identification in Instrument Abbreviations Used in Instrumentation Diagrams. Process diagrams can be broken down into two major categories: process ﬂow diagrams(PFDs) and process and instrument drawings (P&IDs), sometimes called piping and instrumentation drawings.A ﬂow diagram is a simple illustration that uses process symbols to describe the primary ﬂow path through a unit. A process ﬂow diagram provides a quick snapshot of the operating unit. Flow diagrams include.
