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.

The SLF3x enables applications in the fields of diagnostics, analytical instruments and life sciences to reach unparalleled fluid control, system reliability and thus new heights in performance and end-user satisfaction. Its compact form factor and cost-effective design permit system designs with one or more sensors that were previously unfeasible.
