Micro flow switch and bubble detector for liquids
The sensor makes fluidic systems more reliable by enabling the detection of liquid flow within the range of a few ml/min and less. For such measurements the sensor offers a short response time below 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 ¼-28 standard fittings, suitable for connecting plastic tubing with outer diameters of 1/8” (3.2 mm) or 1/6” (1.6 mm). Barb connector adapters are available as an alternative.
