Section 2: Configuration

Configuration
recommended to use the low flow cutoff function in order to have a stable output and avoid
problems due to process noise at a low flow or no flow condition. A low flow cutoff value that is
practical for the flow element in the application should be entered. In this particular example,
the low flow cutoff value is 1000 gallons of water per hour. Based on this information, the Scaled
Variable configuration would be as follows:
Table 2-3. Scaled Variable Configuration for Flow Application
Note
Pressure value position 1 and Scaled Variable position 1 are always set to zero for a flow
application. No configuration of these values is required.
2.6.2 Re-Mapping device variables
The re-mapping function allows the transmitter primary, secondary, tertiary, and quaternary
variables (PV, SV, TV, and QV) to be configured in one of two configurations. The user may select
either the option of Classic Mapping or Scaled Variable Mapping, see Tab le 2- 4 for what is
mapped to each variable. All variables can be remapped with a Field Communicator or AMS
Device Manager.
Table 2-4. Variable Mapping
Note
The variable assigned to the primary variable drives the output. This value can be selected as
Pressure or Scaled Variable.
