Flow Switch and Bubble Detector IC components for Liquids LG01
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.
