Sensirion Product Launch Package: Proximal and Expiratory Flow
Sensors, SFM3xxx-AW, -D versions
The SFM3xxx series is Sensirion’s digital flow meter series designed for medical applications. It
measures the flow rate of air, oxygen and other non-aggressive gases with superb accuracy. The
special design of the flow channel results in a very small dead space.
The SFM3xxx-D is the disposable single-use Version. The re-use version SFM3xxx-AW withstands
washing and autoclaving procedures. It is in development stage with specifications identical to
SFM3xxx-D. Both versions are extremely well suited for proximal flow measurements in medical
ventilation and other respiratory applications.
