Flow Switch and Bubble Detector LG01 for Liquids
The LG01 Flow Switch sensor detects ultra-low liquid flow rates or the presence of air in fluidic systems and 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 whether the current flow rate is above or below the specified flow switch level. At flow rates above this limit the identification of air bubbles within the flow channel is equally consistent. The non-invasive measurement principle of the liquid flow sensor LG01 allows detecting the current state of fluid through the wall of the internal glass capillary. Thus, the sensor provides highest bio-compatibility and chemical resistance. Measurements of the liquid flow detector are performed with a response time of less than 100ms.
