Process engineers use a set of P&ID symbols to draft diagrams.All major components and lines have P&ID symbols.The standards of P&ID symbols and guide process engineers in their plant design activities are covered by the ISA S5.1, ISO 10628, and BS 5070.

The symbology for the identification of the measurement and control instrumentation on the flow and process diagrams is generally compliant with the Standard ISA.

The symbology of the instrument is placed in a circle of 7/16 " or 12mm and there is a functional identification composed of max 5 letters.
