Micro Flow Switch and Bubble Detector

Sensirion (Westlake Village, CA) has launched 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 of under 100 ms. Its output signal of either 0 or 5 volts indicates whether the current flow rate is above or below the specificed flow switch level. Maximum flow rates are accepted up to 220 mL/min. Barb connector adaptations are available as an alternative.
