|Microflow switch and bubble detector|
A sensor manufacturer is launching the LG01 microflow switch for ultralow liquid flow rates and bubble detection. The sensor makes fluidic systems more reliable by enabling the detection of liquid flow within the range of a few milliliters per minute. For such measurements the sensor offers a short response time of less than 100 ms. Its output signal of either 0 or 5 volts indicates whether the current flow rate is above or below the specified flow switch level. At continuous flow rates above this limit, the identification of air bubbles within the flow channel is equally consistent. Maximum flow rates are accepted up to 220 ml/min. Fluidic connections can be made via 1/4-28 standard fittings, suitable for connecting plastic tubing with outer diameters of 1/8 in. (3.2 mm) or 1/6 in. (1.6 mm). Barb connector adapters are available as an alternative.The tiny, lightweight sensor is designed for integration into biomedical applications and general process control solutions.
