ASME Y14.40.6:2002 pdf – GRAPHIiCAL SYIMBOLS FOR DIAGRAMS, PART 6: MEASUREMENT AND CONTROL FUNCTIONS.

This Standard specifies graphical symbols for measurement and control functions in diagrams, with the same symbols in simple applications possibly representing instead components or devices implementing such functions. For graphical symbols for measurement and control components and devices, see ASME Y14.40.5.

For the fundamentai rules of creation and application of graphical symbols in diagrams, see ASME Y14.40.0.

For an overview of the ASME Y14 40 scries, information on the creation and use of registration numbers for identifying graphical symbols used in diagrams, rules for the presentation and application of these symbols, and examples of their use and application, see ASME Y14.40.1.
