In my past experience with similar applications the Combustion Air flow (Linear in Dp Tx) used to interface to DCS I/O to be square rooted in DCS S/w and then corrected for the Temperature before linking to any PID blocks. Is it the right practice or whether to square root at first in the field and then do the Temp correction in the DCS s/w?
Pl. let me know the best practices.
