Overview
Frequency Output Process Variable controls the variable that is reported over the frequency
output.
Prerequisites
If you plan to configure the output to report volume flow, ensure that you have set Volume
Flow Type as desired: Liquid or Gas Standard Volume.
If you plan to configure an output to report a concentration measurement process
variable, ensure that the concentration measurement application is configured so that the
desired variable is available.
If you are using the HART variables, be aware that changing the configuration of Frequency
Output Process Variable will change the configuration of the HART Tertiary Variable (TV).
Procedure
Set Frequency Output Process Variable as desired.
The default setting is Mass Flow Rate.
Options for Frequency Output Process Variable
The transmitter provides a basic set of options for Frequency Output Process Variable, plus
several application-specific options. Different communications tools may use different
labels for the options.
