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 9
9 < Flow Span 90
90 < Flow Span 900
900 < Flow Span
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 m3/h is set for B23/C42: Flow Span
Item | Display content for instantaneous flow rate value |
Auto | 1000 m3/h |
01000 m3/h
11000.0 m3/h
21000.00 m3/h
3With the decimal point removed, 7 digits are not available for the instantaneous flow rate value; therefore, a warning is displayed.

[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 forF10: 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.
