Disposable liquid flow sensors for biomedical applications

Sensirion has unveiled a new disposable liquid flow sensor series equipped with Luer lock fittings for easy integration into the fluidic line and offers fast, precise, and reliable measurement of low and ultralow flow rates. The intelligent, compact, and cost-effective sensors are suitable for a wide range of applications in the biomedical field, from controlling the flow of precious ingredients in bioreactors to monitoring infusion therapies in a clinical environment. The LD20-series CMOSens-based flow sensors optimize costs by reducing the flow sensor to the bare minimum without sacrificing easy fluidic, electrical, and mechanical connections. Standard Luer lock fittings ensure safe and secure incorporation into the fluidic line. The flow channel inside the sensor is completely straight and open and has no moving parts. Medical-grade wetted materials provide outstanding chemical resistance and excellent biocompatibility. By providing a bidirectional measurement of the flow rate from 1200 ml/h down to single-digit ml/h, the sensor reliably detects common failure modes such as occlusion with unprecedented speed and sensitivity, says the company.
