 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 16IW (80%F.S.)

and which uses a differential pressure range of 0 to 2.0 IW, 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.

Set the differential pressure at max. momen-

tary flow rate as 16IW (80%F.S.) ==> Setting item 

Select “3-digit” as decimal point position

of momentary flow rate ==> Setting item 

Set the max. momentary flow rate as “1.000.” ==> Setting item 

Set the low-cut as “10.0%F.S.” of max.

Set the output zero point as “0.0%F.S.”

0 of max. display span* ==> Setting item 

Set the output span point as “100.0%F.S.”

1 of max. display span* ==> Setting item 

Select “SEC” (second) as time factor of

integrated volume ==> Setting item 

Select “1” as weight of flow factor of

integrated volume ==> Setting item 

Select “bt” (manual) as display

switching method ==> Setting item 
