4.2.6 Power Factor for the Flow Law
Screen display: P.FACt
Factory default value: 1.000
This menu is offered if the selected duty is Flow and a profile (e.g. “SPEC.C”) requires the
manual editing of a power factor in the formula:
Flow Q = kh* (where * = the power factor)
The transmitter is pre-programmed with appropriate power factors for many standard flow
profiles, and will automatically select the appropriate factor (See Table 4-1 on page 4-30).
Alternatively, the power factor may be edited to suit a specific flow structure.
