VOLUME_
FLOW
(DS-33)
Indicates the current measured value and status as the primary
value (volumetric flow).
This parameter is input to the AI Function Block and the Totalizer
Function Block.

VOLUME_FLOW_UNITS
This parameter is used in order to select the unit for VOLUME_
FLOW, VOLUME_FLOW_LO_LIMIT and VOLUME_FLOW_HI_
LIMIT parameters.
O/S
See the “Unit”
sheet.
Specified at the
time of order
35
VOLUME_FLOW_LO_LIMIT
This parameter is used in order to enter the lower range value for
volumetric flow.
O/S
-11.88 to 11.88 m/s
or -22.68 to 22.68 m/s
The value depends
on a volume flow unit.
Specified at the
time of order
36
VOLUME_FLOW_HI_LIMIT
This parameter is used in order to enter the upper range value for
volumetric flow.
O/S
-11.88 to 11.88 m/s
or -22.68 to 22.68 m/s
The value depends
on a volume flow unit.
Specified at the
time of order
57
SAMPLING_
FREQ
(DS-33)
This parameter is used in order to indicates the field frequency of the
sensor (Sensor specific, must not be downloaded).

DUAL_FREQUENCY_
MODE
Selection of excitation mode.
This parameter is effective when FLOW_TUBE is “ADMAG AXF”
and NOMINAL_SIZE is in between 25mm to 200mm.
Outside the field of that condition, the warning “71:Meas Mod Set”
will be displayed.
O/S
0: Standerd DF
1: Enhanced DF
0: Standard DF
71
LOW_MF
This parameter is used in order to set the low-frequency meter factor.
This setting is linked with that of parameter CALIBR_FACTOR.
O/S
0.01 to 3.0000

72
HIGH_MF
This parameter is used in order to set the high-frequency meter
factor.
O/S
0.01 to 3.0000
1.0000
73
LOW_MF_EDF
This parameter is used in order to set the low-frequency meter factor
as required when Enhanced DF (i.e., enhanced dual frequency
excitation) is selected. If “Standard DF” has been selected for
Measure_Mode, neither Low_MF(EDF) nor High_MF(EDF) is
displayed.
O/S
0 to 3.0000

74
HIGH_MF_EDF
This parameter is used in order to set the high-frequency meter
factor as required when Enhanced DF (i.e., enhanced dual
frequency excitation) is selected.

SELECT_FLOW_TUBE
This parameter is used in order to set the types of flow tube.
When combining this product with an AXF Remote Flow tube,
“ADMAG AXF” should be selected.
O/S
0: ADMAG AXF
1: ADMAG
2: ADMAG AE
3: ADMAG SE
