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:

Scaled Variable position 2:
Low Flow Cutoff:
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.
2.8.3 Re-mapping device variables
The re-mapping function allows the transmitter primary, secondary, tertiary, and
quaternary variables (PV, 2V, 3V, and 4V) to be configured as desired. The PV can be
remapped with a Field Communicator, AMS Device Manager, or a LOI. Variables (2V, 3V,
and 4V) can only be re-mapped via Field Communicator or AMS Device Manager.
Note
The variable assigned to the primary variable drives the 4–20 mA (1–5 Vdc) output. This
value can be selected as Pressure or Scaled Variable. The 2, 3, and 4 variables only apply if
