�Flow rate range:
10, 25, 50, 100 l /min
�Min. flow measurement: 0.01 l /min
(0.1 l /min when the flow rate range is 25, 50, 100 l /m
in.)
�Fluid: Air, N2, Ar, CO2
�Accuracy (linearity): 3 % F.S.
�Grease-free
�Flow adjustment valve is integrated.
(Reduced piping and space saving)
�Response time: Either 50 msec,
0.5 sec, 1 sec or 2 sec can be chosen. + –
Piping space can be reduced.Mountable in a narrow location since the straight piping length� is not required.
� A straight piping length of 8 times the piping diameter is required for the conventional model.
Compact size(Same size even when the different flow rate model is chosen.)
Comparison with the conventional model PF2A711 (10-100 l /min)when ø6 One-touch fittings are attached.

Light weight: 55 g(PFM711)
Conventional model PF2A711: 290 g
� Mounting methods � Several combinations are possible. Depending on the installation conditions, it is possible to add or remove the flow adjustment valve, change the fitting type and the piping direction as desired.
• 2 NPN or PNP outputs
• 1 NPN or PNP output + Analog (1 to 5 V)
• 1 NPN or PNP output + Analog (4 to 20 mA)

Both of these flow meters display the same value even though fluid pressure differs before and after the regulator.
The displayed value will change before and after the regulator, even though the flow rate is the same.
If located here, the correct value is obtained. (Conversion is required.)
