3.4 Performing Smart Meter Verification
Note: To use Smart Meter Verification, the transmitter must be paired with an enhanced core
processor, and the Smart Meter Verification option must be purchased for the transmitter.
3.4.1 Preparing for the Smart Meter Verification test
The Smart Meter Verification procedure can be performed on any process fluid. It is not necessary to
match factory conditions.
During the test, process conditions must be stable. To maximize stability:
• Maintain a constant temperature and pressure.
• Avoid changes to fluid composition (e.g., two-phase flow, settling, etc.).
• Maintain a constant flow. For higher test certainty, stop flow.
If stability varies outside test limits, the Smart Meter Verification procedure will be aborted. Verify
the stability of the process and retry the test.
Transmitter configuration
Smart Meter Verification is not affected by any parameters configured for flow, density, or
temperature. It is not necessary to change the transmitter configuration.
Control loops and process measurement
If the transmitter outputs will be set to Last Measured Value or Fault during the test, the outputs will
be fixed for two minutes. Disable all control loops for the duration of the test, and ensure that any data
reported during this period is handled appropriately.
3.4.2 Running the Smart Meter Verification test
To run a Smart Meter Verification test:
• With the EDD, refer to Figure 3-4.
• With bus parameters, refer to Figure 3-5 and to Table 3-2.
• With ProLink II, refer to Figure 3-6.
• With the display, refer to Figure B-6.
