Rosemount 8800D
BASIC SETUP The Rosemount 8800D must be configured for certain basic variables in order to
be operational. In most cases, all of these variables are pre-configured at the
factory. Configuration may be required if your Rosemount 8800D is not
configured or if the configuration variables need revision.
Tag Tag is the quickest way to identify and distinguish between flowmeters.
Flowmeters can be tagged according to the requirements of your application.
The tag may be up to eight characters long.
Process Config The flowmeter can be used for liquid or gas/steam applications, but it must be
configured specifically for the application. If the flowmeter is not configured for
the proper process, readings will be inaccurate. Select the appropriate
Process configuration parameters for your application:
Transmitter Mode
For units with an integral temperature sensor, the temperature sensor can be
activated here.
Process Fluid
Select the fluid type: either Liquid, Gas/Steam, Tcomp Sat Steam. Tcomp Sat
Steam requires the MTA Option and provides a temperature compensated
mass flow output for saturated steam.
Fixed Process Temperature
Process Temperature is needed for the electronics to compensate for thermal
expansion of the flowmeter as the process temperature differs from the
reference temperature. Process temperature is the temperature of the liquid
or gas in the line during flowmeter operation.
Fixed process temperature may also be used as a back-up temperature value
in the event of a temperature sensor failure if the MTA option is installed.
NOTE
The Fixed Process Temperature may also be changed under Calculate
Density Ratio.
Density/Density Ratio
When configuring a meter for mass flow units, a density value needs to be
entered. When configuring a meter for Standard and Normal Volumetric flow
units a density ratio will be required.
