6. PARAMETER DESCRIPTION
number of 2 or greater for the next digit to the
right, regardless of the position of the decimal
point.
Example: A value of 333.33 is represented by
the character string 33333, and since
this exceeds 32000, it cannot be set.
In such a case, the value 333.3
should be set instead.
[B24: Flow Decimal Pnt] Setting of the decimal
point position for the instantaneous flow rate
→ This setting is linked with that of parameter C43.
This parameter sets the position of the decimal point
for instantaneous flow rate values in terms of the
number of digits. When set using “Auto”, the decimal
point position will be automatically determined in
accordance with the setting value for B23/C42: Flow
Span as shown below.
Flow Span Յ 9Decimal point position: 3 digits
9 < Flow Span Յ 90 Decimal point position: 2 digits
90 < Flow Span Յ 900 Decimal point position: 1 digit
900 < Flow Span Decimal point position: no
digits (i.e., no decimal point)
When an item other than “Auto” is set, the selected
number of digits for the decimal point position is used.
With the decimal point removed, 6 digits are available
for the instantaneous flow rate value, and display is
possible up to 999,999. If an overflow occurs as a
result of the setting adopted for decimal point position,
the warning 84: Disp Over Wng will be displayed to
provide notification of this condition.
Example: When 1000 m

With the decimal point removed, 7 digits are not
available for the instantaneous flow rate value;
therefore, a warning is displayed.

[B30: Total Unit] Setting of units for totalization
scale

This parameter selects the flow rate units for use in
totalization.

[B31: Total Scale] Setting of the totalization scale
→ This setting is linked with that of parameter D11.
The flow rate is totalized in individual counts in
accordance with this parameter’s setting. If 0 is
selected, it indicates that the totalization function is not
to be used.
NOTE
If a totalization scale is specified upon ordering,
this parameter is set up before shipment; how-
ever, if this is not the case, it will be necessary
for the appropriate value to be set up by the
user.
NOTE
• By setting the totalization scale, the totalized
value is displayed on the display unit. The
totalization scale is determined in accordance
with the settings of B30/D10: Total Unit and
B31/D11: Total Scale.
• The maximum value that can be displayed is
99999999, and if this is exceeded, the value 0
is counted once again. However, counting
stops at 99999999 when the totalization switch
function is used.
• If multiple ranges are being used, the flow rate
span for the smallest range becomes the
standard for the D13: Total Low Cut setting
value.
• Totalization for the reverse flow rate and for the
differential flow rate is carried out only when
“Fwd/Rev Ranges” is selected for F10: SO1
Function or F11: SO2 Function.
• The totalized units are indicated on the display
unit when B31/D11 is 0.001, 0.01, 0.1, 1, 10,
100, or 1000. In the case of other setting
values, the totalized units are not indicated.
