Operation
Filter Restore
Filter Restore enables you to return all of the signal conditioning
variables to their default values. Should the filter settings get confused,
select Filter Restore to restore the default settings and provide a new
starting point.
Damping
Damping function changes the response time of the flowmeter to
smooth variations in output readings caused by rapid changes in input.
The default damping value is 2.0 seconds. Damping can be reset to any
value between 0.2 and 256 seconds.
The appropriate damping setting can be determined based on the
necessary response time, signal stability, and other requirements of the
loop dynamics in your system.
Process Density
Process Density and Density Units are required only if you have
designated mass units for your flow rate units. See Process Density on
page 3-7 or detailed information.
Device Information
Information variables are used for identification of flowmeters in the
field and to store information that may be useful in service situations.
Information variables have no effect on flowmeter output or
process variables.
Manufacturer
Manufacturer is an informational variable provided by the factory.
For the Model 8800C, the Manufacturer is Rosemount.
Tag
Tag is the quickest variable 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.
Descriptor
Descriptor is a longer user-defined variable to assist with more
specific identification of the particular flowmeter. It is usually used in
multi-flowmeter environments and provides 16 characters.
