Rosemount Model 8800C Vortex Flowmeter
3-12
ADVANCED
FUNCTIONALITY
The Model 800C enables you to configure the flowmeter for a wider
range of applications and special situations. These functions are
grouped as follows under Detailed Set-Up:
DETAILED SET-UP • Characterize Meter
• PV Units
• Configure Outputs
• Signal Processing
• Device Information
Characterize Meter The Meter Body variables provide configuration data that are unique to
your Model 8800C. The settings of these variables can effect the
compensated K-factor on which the primary variable is based. These
data are provided during factory configuration and should not be
changed unless the physical make-up of your Model 8800C is changed.
Mating Pipe I.D.
The inside diameter of the pipe adjacent to the flow meter can cause
entrance effects that may alter flowmeter readings. The exact inside
diameter of the pipe must be specified to correct for these effects. Enter
the appropriate value for this variable.
Mating Pipe ID values for schedule 10, 40, and 80 piping are given in
Table 3-1. If the piping in your application is not one of these, you may
need to contact the manufacturer for exact Pipe ID.
K-Factor
The HART 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.
Wetted Material
Wetted Material is a factory set configuration variable that reflects
the construction of your flowmeter.
