Emerson Micro Motion Configuration And Use Manual

- Do not terminate the shielding inside the wiring compartment.
- 360-degree termination of shielding is unnecessary.
• Eliminate the RFI source.
• Move the meter.
10.20 Check the cutoffs
If the density cutoff is configured incorrectly for your process, any density process
variables and any calculations that rely on density may be based on programmed cutoff
values rather than current density data.
Procedure
Verify the configuration of all cutoffs.

10.21 Check for two-phase flow (slug flow)
Two-phase flow can cause rapid changes in the drive gain. This can cause a variety of
measurement issues.
1. Check for two-phase flow alerts (e.g., A105).
If the transmitter is not generating two-phase flow alerts, two-phase flow is not the
source of your problem.
2. Check the process for cavitation, flashing, or leaks.
3. Monitor the density of your process fluid output under normal process conditions.
4. Check the settings of Two-Phase Flow Low Limit, Two-Phase Flow High Limit, and Two-Phase
Flow Timeout.
Tip
You can reduce the occurrence of two-phase flow alerts by setting Two-Phase Flow Low Limit to a
lower value, Two-Phase Flow High Limit to a higher value, or Two-Phase Flow Timeout to a higher
value.
