SLF3S-4000B

SLF3S-4000B is a liquid flow sensor. It is designed for high-volume applications. It enables precise and reliable measurements of dynamic liquid flow rates bi-directionally. The SLF3S-4000B sensor features a digital interface (I2C) via a 6-pin standard electrical connector. The SLF3S-4000B 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. The complete liquid flow sensor portfolio benefits users who want to source their sensor technology from one specialist in automation solutions and fluid systems.
