ter and material, see instruction manual of the fitting S020): the transmitter then calcu-
lates 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 or

a comparison measurement with another flow meter.
The value of the K factor taken into account for the process is the last
