LG01-2000Axxx Liquid Flow Switch and Bubble Detector ■ Detection of low liquid flow in the ml/min Range ■ Totally non-invasive ■ Ultra-fast response time of 100 ms Product Summary The LG01 Liquid Flow Switch enables detection of flow of liquid in the range of ml/min. The output signal is 5V when the flow rate is higher than the specified flow switch point and 0V below this limit or when air or bubbles are found inside the sensor's flow channel instead of liquid. Excellent chemical resistance and bio-compatibility are ensured: The flow path of the LG01 Liquid Flow Switch is formed by a simple, straight glass capillary. For more information on communication, please refer to section 2 of this document. 1 Sensing Performance Table 1: Model specific performance of LG01 (all data for medium . H2O, 23°C)

2 Communication with the Sensor 2.2 Electrical Connector and Sensor Pinout Connector Type: 5 pin Molex PCB Header 53261-0590 Mating connector: Molex 51021-0500. An electrical voltage output indicates flow above (5 V) or below (0 V) the flow switch point and/or air or bubbles inside the sensors flow channel. The product comes fully calibrated for water - for volume applications flow calibration for other media is available on request. a For fluid connection material use flat bottom %-28 standard components e.g. IDEX parts P-200/P-300. Various adapters e.g. to Barb connectors are available from...
