LG01-2000A005

The LG01 liquid flow switch detects ultra-low liquid flow rates or the presence of air in fluidic systems. It therefore makes them more reliable. The detection of liquid flows is possible within the range of a few ml/min and less. The sensor's output signal of either 0 or 5 Volts indicates if the current flow rate is above or below the specified flow switch threshold. At flow rates above the threshold, air bubbles can be identified by generating a low (0V) output. The measurement principle of the LG01 liquid flow switch allows detecting the current state of fluid through the wall of its internal glass capillary. Thus, the sensor provides highest compatibility with biological processes and an excellent chemical resistance. Measurements of the liquid flow switch are performed with a response time of less than 100 ms.
