• Integration is halted during the "FFF" display at the time of

differential pressure range OVER (Refer to paragraph 11.5 (1) ).

• The indicated value which is blinking is integrated during the

"blink" display at the time of momentary flow rate display span

OVER (Refer to paragraph 11.5 (2) ).

(4) Display switching method of momentary flow rate and

integrated volume

Display switching methods of momentary flow rate and integrated

volume include the automatic switching display method to dis-

play them by turns at intervals of fixed time (1 to 10 seconds) and

the manual switching display method to change the display by

pressing (M) key.

䡵 Setting example 3: Standard unit for square root display mode

In the differential flow meter whose differential pressure generated at

maximum momentary flow rate of 120 is 32IW (80%F.S.) and which

uses a differential pressure range of 0 to 40IW, the scaling setting of

the momentary flow rate of standard unit and the setting of integrated

volume of the standard unit are as follows:

In this case, the low-cut is set as 15%F.S., the display switching

method is set as automatic, and the switching time is set as 5 seconds.

Select the “Square root display mode ==> Setting item 

Set the differential pressure at max. momen-

tary flow rate as 32.0IW (80%F.S.) ==> Setting item 

Select “1-digit” as decimal point position

of momentary flow rate ==> Setting item 

Set the max. momentary flow

rate as “120.0.” ==> Setting item 

Set the low-cut as “15.0%F.S.” of

max. display span* ==> Setting item 

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

(0.0 arbitrary unit of measure) of

max. display span* ==> Setting item 
