Configuring the matrix using ProLink IIIFigure 4-1:
Notes
• The matrix is limited to six temperature points, so this matrix represents a subset of the data.
• This example uses an arbitrary value for Reference Temperature.
Results
Fit Results = Good. This indicates that the matrix is mathematically valid.
Fit Accuracy = 0.0. A low value indicates that the referred viscosity values will be highly
accurate.
4.7 Set up the API referral application
The API referral application corrects line density to reference temperature and reference
pressure according to American Petroleum Institute (API) standards. The resulting process
variable is referred density.
• Set up the API referral application using ProLink III (Section 4.7.1)
• Set up the API referral application using the Field Communicator (Section 4.7.2)
