9.1 Record the process variables
Micro Motion suggests that you make a record of specific process variable measurements, including the acceptable range of measurements, under normal operating conditions. This data will help you recognize when the process or diagnostic variables are unusually high or low, and may help you diagnose and troubleshoot application issues.
Procedure
Record the following process and diagnostic variables, under normal operating conditions.
Typical average
Measurement
Typical high Typical low Variable
Flow rate
Density
Temperature
Tube frequency
Pickoff voltage
Drive gain

Scroll to the desired process variable. If AutoScroll is enabled, you can wait until the process variable is displayed. See
View process variables using the display for more information.
View the desired variable on the main screen under Process Variables . See
View process variables and other data using ProLink III
for more information.
Overview → Shortcuts → Variables → Process Variables
Process variables provide information about the state of the process fluid, such as flow rate, density, and temperature, as well as running totals. Process variables can also provide data about flowmeter operation, such as drive gain and pickoff voltage. This information can be used to understand and troubleshoot your process.
9.2.1 View process variables using the display
Procedure
View the desired process variables.
The display shows the configured display variables. For each display variable, the display reports the abbreviated name of the process variable (for example, DENS for density), the current value of that process variable, and the associated unit of measure (for example, G/CM 3 ).

9.2.2 View process variables and other data using ProLink III
Monitor process variables, diagnostic variables, and other data to maintain process quality.
ProLink III automatically displays process variables, diagnostic variables, and other data on the main screen.
Tip
ProLink III allows you to choose the process variables that appear on the main screen. You can also choose whether to view data in Analog Gauge view or digital view, and you can customize the gauge settings. For more information, see the Prolink III user manual .
