Option Description Action
Not Pre-Calibrated Core
Replacement
The core processor and sensor
are being replaced, but the
core processor has not been pre-
calibrated or matched with the
sensor.
The sensor and core processor
are being replaced but the new
core processor has not been
paired (characterized) with the new
sensor.
Enter the sensor parameters and
save the configuration.
I Don't Know You do not know if the new core
processor has been pre-calibrated
and matched with the sensor.
Verify the sensor parameters and
save the configuration if there was
a change.
2. Select Continue.
3. Per the screen message, contact Emerson if you have any questions before you select the Finished
button.
These screens will not display again until another new core processor has been detected.
16.6 Density measurement troubleshooting
16.6.1 Erratic density reading
Cause
• Normal process noise
• Two-phase flow
• Line pressure too low
• The flow rate is too high for the installation
• Pipe diameter too small
• Contaminants or suspended solids in the process gas
• Contaminants or suspended solids in the process fluid
• Vibration in the pipeline
• Erosion or corrosion
Recommended actions
1. Check for alerts.
2. Check your process conditions against the values reported by the device.
3. Decrease the flow rate.
4. Check for two-phase flow.
5. Ensure that line pressure or sample pressure meets installation requirements.
6. Increase back pressure to minimize bubble formation.
7. Minimize vibration in the pipeline.
8. Increase the pipe diameter.
9. Install a flow control method (bypass, flow chamber, expander, etc.).
