Sensirion SLF3S-4000B Compact Liquid Flow Sensor
Sensirion SLF3S-4000B Compact Liquid Flow Sensor is designed for high-volume applications and provides precise, reliable measurements of dynamic liquid flow rates up to 1000ml/min bi-directionally. The SLF3S-4000B sensor features a digital interface (I2C) via a 6-pin standard electrical connector and builds on a CMOSens® sensor chip. 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 ideal for demanding and cost-sensitive OEM applications.Features
