Measurement Performance
10.2.1
Meter verification
Meter verification evaluates the structural integrity of the sensor tubes by comparing current tube
stiffness to the stiffness measured at the factory. Stiffness is defined as the load per unit deflection, or
force divided by displacement. Because a change in structural integrity changes the sensor’s response
to mass and density, this value can be used as an indicator of measurement performance. Changes in
tube stiffness are typically caused by erosion, corrosion, or tube damage.
Notes: To use meter verification, the transmitter must be paired with an enhanced core processor, and
the meter verification option must be purchased for the transmitter.
Micro Motion recommends that you perform meter verification on a regular basis.
There are two versions of the meter verification application: the original version and Micro Motion
Smart Meter Verification. Table 10-1 lists requirements for the original version and Smart Meter
Verification. Table 10-2 provides a comparison of the two versions.
Note: If you are running an older version of ProLink II or the Communicator device description, you
will not be able to access the additional features in Smart Meter Verification. If you are running an
updated version of ProLink II or the Communicator with the original version of meter verification, the
meter verification procedures will be slightly different from the procedures shown here.

Process interruption
No need to halt flow
No need to halt flow
Measurement interruption
Three minutes. Outputs go to:
• Last Measured Value
• Configured Fault Value
User option:
• Continue Measurement. Measurement is
not interrupted. Test requires
approximately 90 seconds.
• Last Measured Value. Outputs fixed and
measurement interrupted for
approximately 140 seconds.
• Configured Fault Value Outputs fixed and
measurement interrupted for
approximately 140 seconds.
Result storage
Test results stored only for tests run with
ProLink II, and stored on the PC
Twenty most recent results stored on the
transmitter, independent of tool used to
perform the procedure. For tests run with
ProLink II, additional result data stored on
PC.
