Product Description
The SLF3S-1300F is Sensirion’s 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. The SLF3S-1300F sensor features a digital interface (I2C) via a 6-pin standard electrical connector. The SLF3S-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.
