Chapter 6
Meter Verification
6.1
Overview
This chapter describes how to use the Structural Integrity meter verification tool. This tool 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.

Micro Motion recommends that you perform meter verification on a regular basis.
Notes: 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 verify that it is installed, use the
Installed Options command on the ProLink II View menu.

This chapter describes meter verification using the Structural Integrity method. The Tools menu
contains a second meter verification method called Known Density Method, which is available only to
authorized service personnel.

Running the meter verification test
To initiate a meter verification test, click on the Tools menu and select
Meter Verification
>
Structural Integrity Method
. This command opens a multi-panel, wizard-style dialog box which will
guide you through the meter verification process.

First panel: Sensor and Transmitter Configuration
The Sensor and Transmitter Configuration panel is shown in Figure 6-1.
This panel displays read-only information about the sensor and transmitter pair you are about to test.
Review this information and make sure it is accurate.
