Emerson Micro Motion Configuration And Use Manual

Problem Possible causes Recommended actions
Inaccurate concentra-
tion measurement
reading
• Inaccurate density measurement
• Inaccurate temperature measurement
• Incorrect reference conditions
• Incorrect matrix data
• Inappropriate trim values
• Verify the line density value. If it is not ac-
curate, see Section 10.7.
• Verify the line temperature value. If it is
not accurate, see Section 10.8.
• Ensure that the application is configured to
use the appropriate temperature source.
• Ensure that reference temperature is con-
figured correctly.
• Ensure that the appropriate matrix is ac-
tive.
• Ensure that the matrix is configured cor-
rectly.
• Ensure that the matrix curve fit is good.
• Adjust the extrapolation limits for the ac-
tive matrix.
• Adjust measurement with a concentration
offset trim. See Section 9.6.
