SMART Meter Verification can be initiated under three possible test conditions. This
parameter is set at the time that the sensor baseline or SMART Meter Verification test is
manually initiated.

No flow
Run the SMART Meter Verification test with a full pipe and no flow in the line. Running the
SMART Meter Verification test under this condition provides the most accurate results and
the best indication of magnetic flowmeter health.
Flowing full
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.
Empty pipe
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.
9.10.2 Test scope
The manually initiated 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.
