Equipment code, medium code, area number – these vary from one design institute to another; each has its own set of design specifications. If it’s not confidential, it can be taken a look at
What do all the legends on the PID homepage mean?
For simple systems, the PID diagram is easy to understand; for complex controls or interlocks, logical explanations are necessary in order to comprehend them. As the demands for automation and safety interlocks increase, PID controllers are becoming increasingly complex.
I can understand a pneumatic butterfly valve, but not the others.
Start with the image on the home page and work your way through it slowly
Just ask how fast the design institute can produce the drawings: lol
This is really… I guess I need to turn to a design firm; I didn’t understand it~
