The symbols must be understood and are defined by the ANSI/ISA-5.1-2009 Standard; however, there is no real standard that specifies how much information and what type of information should be on these drawings. This can cause confusion when a technician is trying to decipher the meaning of a unique symbol that the designer included.
Alla tre delarna kan användas tillsammans eller var för sig. P-regulatorn u(t)=K e(t) Ett exempel med P-reglering visas i Figur 6. Figur 6. P-reglering av syrehalten i en aktivslambassäng.
The symbols used in piping and Instrumentation diagrams or drawings are many and varied. I have dealt with some of these symbols before but here I have given a comprehensive list of the common P&ID symbols of process equipment such as valves, flowmeters, piping line connections, and much more.

The shapes in this legend are representative of the functional relationship between piping, instrumentation, and system equipment units.
Piping and Instrumentation Diagrams are graphical representations of a process system. These are fundamental to every standardized engineering project. These two-dimensional diagrams function as a blueprint for the engineering system’s design.
