6. PARAMETER DESCRIPTION
6.6 Precautions for the
AXF Integral Flow-
meter
Although the AXF integral flowmeter’s software
configurations are the same as the AXFA14, care must
be taken in setting the following parameters:
[C31: Nominal Size Unit] Setting of the nominal
size units
[C32: Nominal Size] Setting of the nominal size
NOTE
The nominal size unit, nominal size and meter
factor have been properly set upon shipment
from the manufacturing plant. Do not change
these parameters.
[C21: Low MF] Setting of the low-frequency meter
factor
[C22: High MF] Setting of the high-frequency meter
factor
[C23: Low MF (EDF)] Setting of the low-frequency
meter factor for enhanced DF (i.e., enhanced dual
frequency excitation)
[C24: High MF (EDF)] Setting of the high-frequency
meter factor for enhanced DF (i.e., enhanced dual
frequency excitation)
NOTE
Setting the meter factor

Meter factors for the AXF integral flowmeter
0038
(1) Confirm that the meter factors indicated on
your AXF integral flowmeter’s data plate has
been set to the parameters.
(2) The meter factors are crucial in ensuring that
the electromotive force is correctly in propor-
tion to the flow velocity and are determined
at the manufacturing plant by actual-flow
calibration.
NOTE
For the hardware configuration of the AXF
integral flowmeter, see the user’s manual of the
AXF Integral Flowmeter [Hardware Edition] (IM
01E20D01-01E).
