LS32-1500 Liquid Flow Meter Compact Flow Meter for Low Flow Rates Liquid flow rates up to 40 ml/min 20 ms response time Excellent repeatability High chemical compatibility Product Summary Interface Options The LS32-1500 enables precise, non-invasive measurements of dynamic liquid flow rates up to 40 ml/min bi-directionally. Excellent biocompatibility is ensured by the exclusive use of high-performance stainless steel, PTFE and PEEK for the wetted parts. The flow path of the LS32-1500 liquid flow sensor is formed by an especially thin-walled, straight tube which assures excellent sensitivity.
