SLF3S-1300D

Upcoming

Manifold mount liquid flow up to 40 ml/min

SLF3S-1300D liquid flow sensor is part of the SLF3x series with manifold mount. This allows reduced assembly cost and complexity by relying on manifolds. Otherwise, the SLF3S-1300D sensor has the same communication interface and performance as the SLF-series and also offers a wide measurement range and milliseconds reaction time.

 

The SLF3x series is the next generation of Sensirion’s liquid flow sensors. By combining Sensirion’s excellent 20-year track record in low and lowest flow rate sensing with a radically optimized mechanical design, the SLF3x takes the well-established functionality to the next level in price-performance ratio. The sensor provides maximum safety, stability and long-term reliability and allows monitoring the entire system operation and detecting common failure modes for a wide range of applications, including the fields of diagnostics, analytical instruments and life sciences.

 

The liquid flow sensors of the SLF3x series are based on Sensirion’s proven CMOSens® Technology and optimize costs by simplifying the design without sacrificing the easy fluidic, electrical and mechanical connections. The straight and unobstructed flow channel has no moving parts; inert wetted materials provide outstanding chemical resistance and excellent media compatibility.
