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.
