10. Check for open or leaking valves or seals.
11. Check for sources of vibration.
12. Verify damping configuration.
13. Verify that the measurement units are configured correctly for your application.
14. Check for two-phase flow.
15. Check for radio frequency interference.
16. Contact customer service.
16.8.5 Inaccurate flow rate
Cause
• Wiring problem
• Inappropriate measurement unit
• Incorrect process variable selection
• Incorrect measurement units
• Incorrect flow calibration factor
• Incorrect meter factor
• Incorrect density calibration factors
• Incorrect grounding
• Two-phase flow
• Problem with receiving device
• Incorrect sensor zero
Recommended actions
1. Check the wiring between the sensor and the transmitter.
2. Verify that the measurement units are configured correctly for your application.
3. Verify all of the characterization or calibration parameters. See the sensor tag or the calibration
sheet for your meter.
4. Zero the meter.
5. Check the grounding of all components.
6. Check for two-phase flow.
7. Verify the receiving device, and the wiring between the transmitter and the receiving device.
8. Check the sensor coils for electrical shorts. If you find problems, replace the sensor.
9. Replace the core processor or transmitter.
