• 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.

Ⅵ 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 32
I W (80%F.S.) and which
uses a differential pressure range of 0 to 40 I W, 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 output zero point as “0.0%F.S.”
(0.0 arbitrary unit of measure) of
max. display span*
