The SLF3S series is the new generation of Sensirion liquid flow sensors for low flow rates. With an unrivaled price-performance ratio, these sensors allow for high-precision flow measurements over a wide range of flow rates.
From 0 to 40 mL/min, the SLF3S-1300F offers a short response time below 20 ms and sensitivity down to 0.05 mL/min.
General
Based on Sensirion's proven CMOSens® technology, the new SLF3x sensor series is the result of Sensirion latest product developments. Its simpler design reduces the cost of this sensor, without compromising its performance. Flow rate is measured through the wall of a straight flow channel, with inert wetted materials for an outstanding chemical resistance.
The SLF3S-1300F is calibrated for water and IPA.
