Understanding SMV results
When the SMV test is completed, the result is reported as Pass, Fail, or Abort. (Some tools
report the Fail result as
Advisory
instead.)
Pass Smart Meter Verification does a statistical check between the factory baseline
value and the current Smart Meter Verification result. Pass indicates that the two
values are statistically the same.
Fail The current SMV value is statistically different than the factory baseline value.
• If the meter passes the second test, the first result can be ignored.
• If the meter fails the second test, the flow tubes may be damaged. Call
customer support.
Abort A problem occurred with the meter verification test (such as process instability)
or you stopped the test manually. See
Table 11‐3 for a list of abort codes, a
description of each code, and possible actions you can take in response.
SMV abort codes Table 11-3:
Code Description Recommended actions
1 User-initiated abort None required. Wait 15 seconds before starting an-
other test.
3 Frequency drift Ensure that temperature, flow, and density are sta-
ble, and rerun the test.
5 High drive gain Ensure that flow is stable, minimize entrained gas,
and rerun the test.
8 Unstable flow Check factors that could cause process instability,
then rerun the test. To maximize process stability:
• Maintain a constant fluid pressure and tempera-
ture.
• Avoid changes to fluid composition, such as
two-phase flow or settling.
• Maintain a constant flow rate.
12 There is a fault present and
SMV cannot run View the Alerts present on the device and take any
necessary actions to clear them.
13 No factory reference data for
meter verification test per-
formed on air Contact customer service.
14 No factory reference data for
meter verification test per-
formed on water Contact customer service.
15 No configuration data for
meter verification Contact customer service.
Other General abort Repeat the test. If the test aborts again, contact
customer service.
