Sensirion AG

Made to Measure – The next generation of liquid flow sensors

The Top 3 Advantages

A radically optimized design allows the next level in price-performance ratio


Bidirectional flow sensing from µl/min up to 40 ml/min within milliseconds


Excellent signal-to-noise ratio and unprecedented turndown ratio

Enables precise dosing and advanced system monitoring in any liquid dispensing system

The SLF3x 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. It allows for precise dosing and accurate monitoring of the entire system including detecting common failure modes for a wide range of applications.

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.
