The commanded Smart Meter Verification test can be used to verify the entire flowmeter
installation or individual parts such as the transmitter or sensor. This parameter is set at
the time that the Smart Meter Verification test is manually initiated. There are three test
scopes from which to choose.

Continuous Smart Meter Verification

Continuous Smart Meter Verification can be used to monitor and verify the health of the
flowmeter system. The continuous Smart Meter Verification will not report results until 30
minutes after powering up to ensure the system is stable and to avoid false failures.

most accurate results and the best indication of magnetic flowmeter
health.
Run the Smart Meter Verification test with a full pipe and flow in the line.
Running the Smart Meter Verification test under this condition provides the
ability to verify the magnetic flowmeter health without shutting down the
process flow in applications when a shutdown is not possible. Running the
diagnostic under flowing conditions can cause a false test failure if there is
significant process noise present.
Run the Smart Meter Verification test with an empty pipe. Running the
Smart Meter Verification test under this condition provides the ability to
verify the magnetic flowmeter health with an empty pipe. Running the
verification diagnostic under empty pipe conditions will not check the
electrode circuit health.

Run the Smart Meter Verification test and verify the entire flowmeter
installation. This parameter results in the diagnostic performing the
transmitter calibration verification, sensor calibration verification, coil
health check, and electrode health check. Transmitter calibration and
sensor calibration are verified to the percentage associated with the test
condition selected when the test was initiated. This setting applies to
manually initiated tests only.
Run the Smart Meter Verification test on the transmitter only. This
results in the verification test only checking the transmitter calibration
to the limits of the test criteria selected when the verification test was
initiated. This setting applies to manually initiated tests only.
Run the Smart Meter Verification test on the sensor only. This results in
the verification test checking the sensor calibration to the limits of the
test criteria selected when the Smart Meter Verification test was
initiated, verifying the coil circuit health, and the electrode circuit
health. This setting applies to manually initiated tests only.
