10.16 Checking the output wiring and receiving device
If you receive an inaccurate mA reading, there may be a problem with the output wiring, the output
scaling, or the receiving device.
• Check the output level at the transmitter.
• Review the information on mA output scales (see Section 3.4) and verify that the receiving
device is programmed to interpret the mA output correctly.
• Check the wiring between the transmitter and the receiving device, including all wiring at the
I.S. barrier or Micro Motion adapter-barrier (if applicable).
• If an I.S. barrier or Micro Motion adapter-barrier is installed, test the signal between the
transmitter and the barrier, then between the barrier and the receiving device.
• If required, trim the mA output or calibrate the barrier.
• Try a different receiving device.
• Use sensor simulation to locate the problem. See Section 10.11.
10.17 Checking slug flow
A slug flow alarm is posted whenever the measured process density is outside the configured slug
flow limits (i.e., density is higher or lower than the configured normal range). Slug flow is typically
caused by gas in a liquid process or liquid in a gas process. See Section 4.7.4 for a discussion of slug
flow functionality.
If slug flow occurs:
• Check the process for cavitation, flashing, or leaks.
• Change the sensor orientation.
• Monitor density.
• If desired, enter new slug flow limits (see Section 4.7.4).
- Raising the low slug flow limit or lowering the high slug flow limit will increase the
possibility of slug flow conditions.
- Lowering the low slug flow limit or raising the high slug flow limit will decrease the
possibility of slug flow conditions.
• If desired, increase slug duration (see Section 4.7.4).
