Could everyone please help explain the symbols in the process flow diagram?

What do FFC and FFR mean between two FC control points in a chemical process flow diagram? ? Also, what does DP mean in process control? How should “plant at grade” be translated in a floor plan? ? Cross-section of the ground plane device? ? It would be best to provide the words represented by each letter (except for flowrate, contron, recorder, and pressure)
How is it that no one knows?/???
Hey, could you send me the document HG20505-92 titled \"Alphanumeric Codes and Graphic Symbols for Process Detection and Control Systems\"? The website you gave me doesn’t work. My email address is bruceliu1112@163.com. Of those two words that start with F, besides \"flowrate\", what word is the other one an abbreviation for??
It seems to mean traffic as well; the friend on floor 3 might want to upload this standard – it seems HaiChuan doesn’t have it yet.
I have revised the link; just copy the address and paste it into the browser’s address bar to open and download it! (The original method caused an error when opening it)
