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. Interface Options Digital Analog - I2C-Bus - Voltage output (0-10 V) - RS485-Bus - Current Output 4-20 mA (0-20 mA) - USB Cable - Additional operation modes For more information on communication, please refer to page 5 of this document.
