4.1.7 Shed freq at URV
Gives the shedding frequency corresponding to your URV (URV = Upper Range Value). If the
PV is Process Temperature, the Shedding Frequency at URV represents the shedding
frequency of the Volumetric Flow URV. This can be set by assigning Volumetric Flow to PV
and setting range values.
4.2 Advanced functionality
The Rosemount 8600D enables you to configure the flowmeter for a wider range of
applications and special situations. These functions are grouped as follows under Detailed

Device Information
4.3.1 Characterize meter
The meter body variables provide configuration data that are unique to your Rosemount
8600D. The settings of these variables can affect the compensated K-factor on which the
primary variable is based. This data is provided during factory configuration and should not
be changed unless the physical make-up of your Rosemount 8600D is changed.
K-factor
The Field Communicator provides information on Reference and Compensated K-factor
values.
The Reference K-factor is factory set according to the actual K-factor for your application. It
should only be changed if you replace parts of the flowmeter. Contact your Rosemount
representative for details.
The Compensated K-factor is based on the reference K-factor as compensated for the given
process temperature, wetted materials, body number, and pipe ID. Compensated K-factor
is an informational variable that is calculated by the electronics of your flowmeter.
