Output Voltage Characteristics
D6F-V03A1
The flow velocity is the value calculated from the mass flow rate in OMRON’s
specified 48-mm-dia. wind tunnel. It does not indicate the flow velocity deter-
mined by the Measurement Law of Japan. The wind tunnel conditions are
shown in Figure 1 below.
Measurement conditions: Power supply voltage of 3.3 VDC, ambient tempera-
ture of 25°C, and dry air.
RoHS Compliant
Refer to the Common Precautions for the D6F Series on page 40.
