Reading and interpreting Smart Meter Verification test results

Pass/Fail/Abort
When the Smart Meter Verification test is completed, the result will be reported as Pass, Fail/Caution
(depending on the tool you are using), or Abort:
• Pass – The test result is within the specification uncertainty limit. In other words, the stiffness
of the left and right pickoffs match the factory values plus or minus the specification
uncertainty limit. If transmitter zero and configuration match factory values, the sensor will
meet factory specifications for flow and density measurement. It is expected that meters will
pass Smart Meter Verification every time the test is run.
• Fail/Caution – The test result is not within the specification uncertainty limit. Micro Motion
recommends that you immediately repeat the Smart Meter Verification test. If you previously
set outputs to Continue Measurement, change the setting to Last Measured Value or Fault.
- If the meter passes the second test, the first Fail/Caution result can be ignored.
- If the meter fails the second test, the flow tubes may be damaged. Use your process
knowledge to determine the possibilities for damage and the appropriate actions for each.
These actions might include removing the meter from service and physically inspecting
the tubes. At minimum, you should perform a flow validation and a density calibration.
• Abort – A problem occurred with the Smart Meter Verification test (e.g., process instability).
Abort codes are listed in Table 3-3, and suggested actions are provided for each code.

Suggested action
None required. Wait for 15 seconds before starting
another test.
Ensure that temperature, flow, and density are stable,
and rerun the test.
Ensure that flow is stable, minimize entrained gas, and
rerun the test.
Review the suggestions for stable flow in Section 3.4.1
and rerun the test.
