Sensirion releases next-generation liquid flow sensor with diagnostic applications

Sensirion, a leading manufacturer of flow and environmental sensors, has announced a new product variant in the SLF3x series: the SLF3S-0600F liquid flow sensor. The SLF3S-0600F is said to measure very low flow rates bidirectionally up to ±3000 µl/min and offer the same impressive features as the existing SLF3S-1300F sensor. This makes the new sensor suitable for a wide range of applications in diagnostics, analytical instruments and life sciences. The first prototype samples of the SLF3S-0600F are now available for testing. The new product variant will be available for distribution in the second half of 2020.

The SLF3x is Sensirion’s latest innovation in liquid flow sensing. Based on Sensirion’s excellent 20-year track record in low and lowest flow rate sensing, the radically optimized mechanical design of the SLF3x takes an already well-established functionality to the next level in terms of price-performance ratio. The sensors in the SLF3x series are based on Sensirion’s CMOSens® Technology and optimize costs by simplifying the design without sacrificing performance or having to forgoing any user-friendly fluidic, electrical and mechanical connections.

The new sensor allows for the bidirectional measurement of flow rates up to ±3000 µl/min for both water and hydrocarbon-based fluids. In combination with its excellent signal-to-noise ratio and unprecedented turndown ratio of 300:1, it allows real-time monitoring of any fluidic system, which improves process control and enables advanced failure detection. The straight, unobstructed flow channel has no moving parts and is made from inert wetted materials that provide outstanding chemical resistance and excellent media compatibility.

The SLF3x sensor series provides an unparalleled level of fluid control, system reliability, performance and end-user satisfaction for a range of applications in the fields of diagnostics, analytical instruments and life sciences. The ultra-compact form factor and cost-effective design pave the way for system designs featuring one or more sensors, which were previously unfeasible. The first prototype samples of the SLF3S-0600F are now available for testing, the new product variant will be available for distribution in the second half of 2020.​​​​​​
