New product launch: experience liquid flow sensing on a new level

We launched our first liquid flow sensor that measures flow rates up to 1l/min – the SLF3S-4000B.

We closed the gap of flow sensors for higher flow rates in laboratory analysis and industry with the cost-effective SLF3S-4000B liquid flow sensor. It accurately measures flow rates up to 1 l/min with the usual quality, while measuring just 5 cm in length and weighing 7 g. The newest addition to our SLF3x family will soon be available via distribution. Until then, learn more about the SLF3S-4000B and its special features in our webinar, our specialist article and in the datasheet.

Made to measure: the next level in liquid flow sensing

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.

SLF3S-4000B

Liquid flow sensing on a new level: flow rates up to 600 ml/min

With the new SLF3S-4000B high-flow sensor, Sensirion is moving into a new measurement dimension and now covers an extended measurement range from nanoliters to liters per minute. With the same look and feel as the existing SLF3x flow sensor family, the SLF3S-4000B offers several advantages. Users can continue to use existing cables or software for readout without customization, thus eliminating reprogramming processes. The complete liquid flow sensor portfolio benefits users who want to source their sensor technology from one specialist in automation solutions and fluid systems.
