Rosemount 8800D
LFC Response
Defines how the output of the Vortex meter will behave entering into and
coming out of the Low Flow Cutoff. Options are stepped or damped. (See
Technical Note 00840-0200-4004 for more information regarding Low Flow
Measurement).
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
Rosemount 8800D, 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.
Message
The Message variable provides an even longer user-defined variable for
identification and other purposes. It provides 32 characters of information and
is stored with the other configuration data.
Date
Date is a user-defined variable that provides a place to save a date, typically
used to store the last date that the transmitter configuration was changed.
Write Protect
Write Protect is a read-only informational variable that reflects the setting of
the hardware security switch. If Write Protect is ON, configuration data are
protected and cannot be changed from a HART-based communicator or
control system. If Write Protect is OFF, configuration data may be changed
using the communicator or control system.
