Sensirion SLF3x Series Liquid Flow Flow Sensor for Liquid, 0.04 L/min Max

The Sensirion is a compact liquid flow sensor designed for high-volume applications. It enables precise and reliable measurements of dynamic liquid flow rates up to 40 ml/min bi-directionally. Additionally, this version of the SLF3x family sports thermal conductivity feature that enables the measurement of concentrations or distinguishing between different liquids. The SLF3C-1300F sensor features a digital interface (I2C) via a 6-pin standard electrical connector. The SLF3C-1300F builds on the latest generation CMOSens sensor chip that is at the heart of Sensirion’s flow sensing platform and allows achieving an outstanding performance. The patented CMOSens technology combines the sensor element, signal processing and digital calibration on a small CMOS chip. The well-proven CMOS technology is perfectly suited for high-quality mass production and is the ideal choice for demanding and cost-sensitive OEM applications.
