4.4.3 K-Factor

The menu makes it possible to determine the K factor of the process:
either by entering the value of the K factor of the fitting (depending on the pipe
A
diameter and material, see instruction manual of the fitting S020): the transmitter
then calculates the K factor for the process using the fitting K factor, the cell
constant Fs and the temperature coefficient Kw.
Fs and Kw are set ex works and can be read and modified within the TEST menu.
or by using the „TEACH-IN" procedure. It consists either of a volume measurement
B
or a comparison measurement with another flow meter.
The value of the K factor taken into account for the process is the last determined K
factor, whatever the method used.
