Scale factor / K-factor (P013)
Level measurement
When the process value (PV) is a level measurement in meters, feet, or inches, this parameter
converts (scales) the level measurement into alternative units before being output. Enter a value
of 1.0 if alternative units are not required.
Volume measurement
When the PV is a volume measurement from a
standard non-linear-shaped
tank e.g. cylinder or
sphere, use this parameter to enter the volume of the ideal shaped tank (
).
When the PV is a volume measurement from a
regular-shaped
tank e.g. square or rectangular,
use this parameter to enter the volume change per unit of the base unit.
When the PV is a volume measurement from an
irregular-shaped
tank, use this parameter to
enter the maximum volume. See also the Special Plot section on
for defining the
irregu-
lar-shaped
tank.
Open channel measurement
When the PV is the flow rate in a
standard
open channel, use this parameter to enter the scale
factor (‘k’ term) in a flow rate calculation. See
for selecting a
standard flow profile.
When the PV is the flow rate in an
irregular-shaped
open channel, use this parameter to enter the
maximum flow rate. See also the Special Plot section on
for defining the
irregu-
lar-shaped
channel.
