Quick Start Guide
Transmitter scale factor / K-factor (P013)
Level measurement
When the process value (PV) is a level measurement in meters, feet, or inches, this
parameter converts 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
(Figure
11).
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 relating to the Profile Height

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
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
the irregular-shaped channel.
