Smart Meter Verification has an output mode called Continuous Measurement that allows the
transmitter to keep measuring while the test is in progress. If you choose to run the test in
Last Measured Value or Fault modes instead, the transmitter outputs will be held constant for
the two minute duration of the test. If control loops depend on transmitter outputs, take
appropriate action.
Avoid process instability during the test. If conditions are too unstable, the Smart Meter
Verification test will abort. To maximize process stability:
• Maintain a constant fluid pressure and temperature.
• Avoid changes to fluid composition, e.g., two-phase flow or settling.
• Maintain a constant flow rate.
Tips
• The Smart Meter Verification test runs best when flow is stopped through the sensor.
• Smart Meter Verification is not affected by any configured transmitter parameters for flow,
density, or temperature.
9.2.3 Run Smart Meter Verification

1. Choose Tools > Meter Verification > Run Meter Verification.
You may need to wait a few seconds while ProLink II synchronizes its database with
the transmitter data.
2. Review the information presented on the screen, and click Next.
3. Enter any desired information on the Test Definition screen, and click Next.
All information on this screen is optional.
4. Choose the desired output behavior.
Option Description
Outputs Continue
Measuring
During the test, all outputs will continue to report their assigned proc-
ess variable. The test will run for approximately 90 seconds.
Outputs Held at Last
Value
During the test, all outputs will report the last measured value of their
assigned process variable. The test will run for approximately
140 seconds.
Outputs Held at Fault
During the test, all outputs will go to their configured fault action. The
test will run for approximately 140 seconds.
5. Press Start Meter Verification.
