Emerson Micro Motion 1600 - 16.6.2 Inaccurate density reading; 16.6.3 Unusually high density reading

10. Perform Smart Meter Verification.
16.6.2 Inaccurate density reading
Cause
• Problem with process fluid
• Incorrect density calibration factors
• Wiring problem
• Two-phase flow
• Plugged or coated sensor tube
• Incorrect sensor orientation
• RTD failure
• Physical characteristics of sensor have changed
Recommended actions
1. Check the wiring between the sensor and the transmitter.
2. Check the grounding of all components.
3. Check your process conditions against the values reported by the device.
4. Ensure that all of the calibration parameters have been entered correctly. See the sensor tag or the
calibration sheet for your meter.
5. Check for two-phase flow.
6. If two sensors with similar frequency are too near each other, separate them.
7. Purge the sensor tubes.
8. Perform Smart Meter Verification.
16.6.3 Unusually high density reading
Cause
• Plugged or coated sensor tube
• Incorrect density calibration factors
• Inaccurate temperature measurement
• RTD failure
• In high-frequency meters, erosion, or corrosion
• In low-frequency meters, tube fouling
Recommended actions
1. Ensure that all of the calibration parameters have been entered correctly.
See the sensor tag or the calibration sheet for your meter.
2. Purge the sensor tubes.
3. Check for coating in the flow tubes.
4. Perform Smart Meter Verification.
