Transmitter operation
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 include data about flowmeter
operation, such as drive gain and pickoff voltage. This information can be used to understand and
troubleshoot your process.
Procedure
View the desired process variable(s).
If you are using the transmitter display, by default the display shows the mass flow rate, mass total,
volume flow rate, volume total, temperature, density, and drive gain. If desired, you can configure
the display to show other process variables, such as totalizers and inventories. 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/CM3
). If
Auto Scroll
is
enabled, the display cycles through the configured display variables, showing each display variable for
a user-specified number of seconds.
Figure 8-1 identifies the features of the transmitter display.
