SLS-1500 Liquid Flow Meter
Compact Flow Meter for Industrial Applications
 Liquid flow rates up to 40 ml/min
 20 ms response time
 High chemical compatibility
 Modular electrical interface
Product Summary
The SLS-1500 liquid flow meter 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 SLS-1500 liquid flow sensor is
formed by an especially thin-walled, straight tube which
assures excellent sensitivity.
