4 COMMISSIONING
Fitting Factor-K (see Fig. 4.4 )
The fitting factor (K) adjusts the pulses generated by the paddle wheel to the electronic
system. The fitting factor indicates how many pulses the paddle wheel emits per volume
flow. The volume unit for the flow rate is determined by the fitting factor and does not
therefore have to be given in addition. Any unit can be used (ml, l, m
(K-factor value: refer to the instruction manual type S020; 1500; 1501 according to fittings
type used).
Time Unit (see Fig. 4.3)
The time unit is selected from hours (h), minutes (m) and seconds (s).
The time unit is continuously displayed while in standard mode.

Lower Range Value (4 mA)
The lower range value determines which flow rate value is allocated to the 4mA output
signal. Its unit is determined by the previously set data (fitting factor and time unit).
Upper Range Value (20 mA)
The upper range value determines which flow value is allocated to the 20 mA output signal.
Its unit is the same as that for the lower range value. The upper range value must always
be greater than the lower range value.
The control unit can be removed from the 8023 flow rate transmitter, e.g. after programming
has been completed, without affecting the set process. The housing cover must then be
placed back on the device and screwed in place.
The programmed values are stored in the flow rate transmitter.
