Sensirion SLI liquid flow sensor is a high-precision standalone solution to accurately measure low flow rates of liquids based on water or hydrocarbons. Its wide flow range, its short response time of 40 ms, and its sensitivity down to < 1 µL/min make it the ideal sensor for your microfluidic setup.
Available in 3 versions according to the flow range: 0-80 µL/min, 0-1000 µL/min, or 0-5000 µL/min.
General
Sensirion sensors are based on the unique CMOSens® technology, allowing short response times and outstanding performances. Flow rate is measured through the wall of a straight glass capillary path, to ensure excellent chemical resistance.
The SLI flow sensor is a standalone device for flow rates ranging from µL/min to mL/min: connect the sensor to your computer with the SCC1 cable, and control it from the Sensirion ControlCenter software. It is available in 3 versions, calibrated for water and IPA.
