Liquid flow sensor delivers accuracy to within 5%

The LD20-2600B is a highly accurate, single-use, streamlined sensor for high-volume medical, life-science or food industry applications.

This high-performance liquid flow sensor delivers full-scale accuracy within 5% (H₂O), with 0.5% repeatability (H₂O), utilizing a 6000 μA maximum supply current and a straight, unobstructed flow channel with no moving parts.

It features CMOSenstechnology combining the sensor element, signal processing and digital calibration on a small CMOS chip. The sensor provides a bidirectional measurement of flow rates from 1000 ml/h down to single-digit ml/h while also detecting common failure modes, such as occlusion, free flow or air bubbles, with unprecedented speed and sensitivity.

The single-use sensor measures the liquid flow rate directly and at the point of interest for more effective patient treatment and improved safety, and it provides data on a digital I²C interface via metal contact pads.

Drug delivery can be measured precisely and in real-time.

Consequentially, therapies become more effective and easier to monitor and control.

The sensor enables medical device manufacturers to enhance the safety, performance, and reliability of their products for the benefit of patients and caregivers.

Low-power consumption, makes the sensor suitable for battery-powered applications. It is made from medical-grade, chemically resistant wetted material and offers high reliability and long-term stability.

The LD20 Base Station, available to order from Mouser, is used to evaluate and test the LD20-2600B liquid flow sensor. The connector block mechanically holds the sensor in place through a clip-in mechanism and provides an electrical interface between the sensor's contact pads and a PC. The Base Station features mounting holes enabling the user to anchor it to a workbench and features basic electrostatic discharge protection.
