Meter Verification
6.1 Overview
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:
(1) To use meter verification, the transmitter must be paired with an enhanced core processor, and the
meter verification option must be installed on your transmitter. To check whether this option is
installed, choose
View > Installed Options .
(2) Micro Motion recommends that you perform meter verification on a regular basis.
The availability of meter verification, and the specific features presented by meter verification, depend
on the transmitter. For information about performing the meter verification test with your transmitter,
refer to the transmitter manual.
