Inaccurate density measurement
Inaccurate temperature measurement
Incorrect reference conditions
Incorrect API table selection
Recommended actions
• Check your process conditions against the
values reported by the device.
• Verify the configuration of the API referral
application and related parameters.
• Verify the line density value.
• Verify the line temperature value.
• Ensure that the application is configured to
use the appropriate temperature source.
• Ensure that the pressure source is config-
ured correctly, that the external pressure
device is operating correctly, and that both
devices are using the same measurement
units.
• Ensure that reference temperature and ref-
erence pressure, if applicable, are config-
ured correctly.
• Ensure that the selected API table is appro-
priate for the process fluid.
Recommended actions
Set the temperature and density units to the
units used when the matrix was built, then re-
load the matrix. For custom matrices, contact
customer support.
