Sensirion's liquid flow sensor LG01 is a simple and cost-efficient solution to detect liquid flow. The micro flow switch is able to identify whether liquids are within the flow channel or not. Even the detection of bubbles is possible. The non-invasive measurement principle allows detecting the current state of fluid through the wall of the internal glass capillary with a maximum flow rates up to 220 ml/min. The fluidic connectors made of PEEK high-end plastics make the sensor perfectly fit for the integration into bio-medical applications and general process control solutions.
