Sensirion Announces Its New Liquid Flow Sensor

The SLF3S-1300F liquid flow sensor is based on Sensirion’s proven CMOSens® Technology and optimizes 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. In measuring flow rates up to 40 ml/min bi-directionally, the sensor allows monitoring the entire system operation and detecting common failure modes.

The SLF3S-1300F 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.

Samples of the SLF3S-1300F liquid flow sensor are available now for testing. Please contact Sensirion for further information at info@sensirion.com.
