For Air
High Flow Rate Type (For Air)
High Temperature Fluid Type (For Water)
Note) Fixed SI unit [l/min or l] will be set for the type
Note 1) Applicable for all integrated display types other than series
Note 2) Only for series PF2A7H.
Functions:
Real-time flow rate and accumulated flow rate can be selected.
Up to 999999 of flow rate value can be accumulated.
CFM = ft
GPM
Basic state: 0°C, 101.3 kPa
Standard state: 20°C, 101.3 kPa, 65%RH (ANR)
Switchable between these states.
This function allows to confirm the accumulated flow rate
when real-time flow rate is selected and to confirm the
real-time flow rate when accumulated flow rate is selected.
This function prevents incorrect operations such as
changing the set value accidentally.
This is to clear the accumulated value.
This is to restore the setting to the initial state when
dispatched from the factory.

The setting data has
changed for whatever
reasons.
The flow rate is over the
flow rate measurement
range (for air only).
A current of more than
80mA is flowing to OUT1
A current of more than
80mA is flowing to OUT2.

Check the load and wiring
for OUT2.
Perform the RESET
operation, and reset all
data again.
Reduce the flow rate until it
is within the flow rate
measurement range, using
an adjustment valve.
