Micro Flow Switch Measures Ultra Low Flow Rates and Detects Bubbles

Thu, 05/26/2011 - 11:34am


Sensirion AG is launching the LG01 micro flow switch for ultra-low 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 ml/min and less. For such measurements, the sensor offers a short response time below 100 ms. Its output signal of either 0 V or 5 V 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. The light sensor is designed for integration into bio-medical applications and general process control solutions. The new product is based on a digital MEMS chip.
