The paddle style flow switch, series IF3 detects and confirms liquid
flow. The series is generally used in fields such as air conditioning,
water supply equipment, etc. Enclosures include a standard type for
indoor applications away from moisture; drip proof (JIS C0920) which
can tolerate water drip in indoor or outdoor applications; and splash
proof (JIS C0920) which has a sealed construction that can tolerate
hosing or salt laden atmospheres.

IFW series flow switches detect and confirm liquid flow. They are
applicable to general industrial machines and various other
applications. The IFW series will detect the flow of water and other
non-corrosive fluids. The detection range is from 1 to 50 liters per
minute. The flow setting can be adjusted with a screwdriver from the
outside of the unit without removing the cover.

SMC's new InfiniFlow™ ultrasonic flow sensing technology incorporates a
cutting-edge contrapropagating cross-correlation measurement method.
This technology is up to 20 times faster than the industry standard
"sing-around" method. In addition, the cross-correlation method is much
more efficient in data collection and processing, even under adverse
conditions with micro-bubbles. The system is an "All-SMC" fully
integrated technology. By a simple change on the Windows™ utility
screen, you can switch from stand-alone sensor mode to closed-loop
mode, and with the addition of the LTV20 hybrid regulator, you will be
controlling liquid flow with superior accuracy and repeatability. This
is accomplished using the same compact controller for either mode, and
there is no "hand-shaking" with a separate PID controller.

SMC offers a variety of digital flow switches. Series PF2A for air,
PF2W for water, PF2D for deionized water and chemicals. Flow rate
setting and monitoring are possible with the digital display.
Integrated and remote type displays are available for different types
of application. Water resistant construction is used conforming to IP65
protection. Switching from real-time flow rate to accumulated flow is

Applications requiring a constantly monitored flow of cooling or
cleaning water now have the perfect solution with the launch of the new
PF3W Digital Flow Switch Series from the world leaders in pneumatics -
Developed following the success of SMC’s PF2W flow switch range, their
R&D engineers have now taken these flow switches to a new level by
improving both their design and operating performance.
Depending on the selected model, the new Series PF3W is now up to 40%
smaller in volume than the previous range thereby offering improved
piping space and flexibility.
Designed to work with fluids up to 90ºC, these switches incorporate an
in-built temperature sensor so that both flow and fluid temperature can
be effectively monitored at the same time. According to SMC engineers,
pressure losses have also been reduced when compared to the previous
range and the new PF3W can also be used with ethylene glycol operating
fluid making these switches ideal for use in chiller type applications.
Further improvements include the addition of two screens incorporating
three colour numerical displays which can also be rotated in both
clockwise and anti-clockwise directions thereby offering even better
display visibility during operation.
Available as non grease type and with analogue output if required, the
new Series PF3W range meets IP 65 enclosure protection standards and are
both RoHS and CE compliant.

SMC's PFM dual color digital flow switch was developed initially to
detect microchip component adsorption in vacuum, and early clogging in
both filter and nozzle applications. The series is incredibly compact
and lightweight compared to existing flow sensors. The PFM is
available in four maximum flow rate options 10, 25, 50 and 100 ℓ/min, and is suitable for use with air, nitrogen, argon or carbon dioxide.

Answering the demands for a pressure sensor that would send an output
over a wide range where most pressure sensors could not send a signal
when adsorbing minute work pieces, SMC has designed the PFMV5 series.
The PFMV5 is a small flow sensor with a rapid response time of less
than 5ms. The PFMV5 series is mountable in a space-saving location
since the straight piping length is not required. The
PFMV3 voltage monitor for the PFMV5 series can cover a full range of
sensors (6 ranges). The sensor connector offers easy connection and
removal of wiring. The dual color display (red and green)allows for
visual confirmation of the current condition.
