ባ Setting of integrated volume
When a momentary flow rate unit is set as an arbitrary unit, the
integrated volume is also an arbitrary unit and the factor of the
two following points must be set:
• Setting of time factor (second, minute, hour)
• Setting of flow factor weight (1, 10, 100, 1000)
In the differential flow meter whose differential pressure generated
at maximum momentary flow rate of 1.000L/s is 16
I W (80%F.S.)
and which uses a differential pressure range of 0 to 2.0 I W, the
setting of momentary flow rate of arbitrary unit and the setting of
integrated volume of the arbitrary unit (in order to display 1 per
count) are as follows: In this case, the low-cut is set as 10%F.S.
and the display switching method is set as manual.
