Flow/Volume measurement via API tables

Hello,

I am working on a project where I need to be able to do compensation according to the API tables. I don't see any function blocks in DeltaV that provide this. Is there a way to interface with these tables and get the appropriate correction factors?

Thanks,

Dave

  Dave,

  I was looking for the same thing awhile back.  I ended up using the following document:

  

  The document list out coefficients based upon product grouping.

  

  Prior to the table it shows the different formulas to use and examples to go by.  This is what I ended up doing for tank volume correction based upon temperature.

  Micromotion flow meters have this capability built in if you order it. You can set the raw or compensated flow as the 4-20 and bring the rest in via HART.
