Profile height / Power factor (P014)
Level measurement
This is not used for level measurements. It does not appear on the Field Communicator
unless required for volume or flow measurements.
Volume measurement
When the process value (PV) is a volume measurement from a standard
non-linear-shaped tank e.g. an ideal horizontal cylinder or a sphere, use this parameter
to enter the diameter (see Figure 11 on page 16 ).
When the PV is a volume measurement from a regular-shaped tank e.g. square or
rectangular, this parameter is not used.
When the PV is a volume measurement from an irregular-shaped tank, use this
parameter to enter the maximum height. See also the Special Plot section on page 19
for defining the irregular-shaped tank.
Open channel measurement
When the PV) is a flow rate in a standard open channel, this parameter is used as the
power factor (‘pwr’ term) in a flow rate calculation. See page 14 for selecting a flow
profile.
When the PV is the flow rate in an irregular-shaped open channel, use this parameter to
enter the maximum height. See also the Special Plot section on page 19 for defining
the irregular-shaped channel.
