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
The LS32-1500 enables precise, non-invasive mea-
surements 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.
