Disposable Liquid Flow Sensors for Biomed Applications

Sensirion AG has launched an updated version of its LD20 disposable liquid flow sensor series, now equipped with luer lock fittings for easy integration into the fluidic line, offering 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.

Sensirion’s liquid flow meters are being used in numerous challenging applications, from diagnostic instruments to process control in the semiconductor industry.
