�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.)

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.)
