The petrochemical instrument chart is slightly different from the traditional habits of various design institutes, but in general, it should at least have the following contents:
Schematic diagram of measurement and control with flow chart; Control cabinet diagram (can also be classified as the former); Measurement and control layout (including instrument and equipment material list, etc.). ); Installation drawing (because there are standard installation details for reference, it can be omitted or marked unless it is special or necessary).
