Based on Sensirion's proven CMOSens® technology, the new SLF3x sensor series is the result of Sensirion latest product developments. Its simpler design brings down the cost of this sensor, without any compromise on the performances. Flow rate is measured through the wall of a straight flow channel, with inert wetted materials for an outstanding chemical resistance.

The SLF3x series is declined in 2 versions, calibrated for water and IPA:
