SLx – Standalone Liquid Flow Meters
The SLI, SLS, SLQ, and SLG liquid flow meters all feature a robust IPxx protected housing and the same 4-pin M8 connector. In combination with the SCC1-USB, RS485, or analog sensor cables, they provide a modular solution that covers a wide range of flow rates from single-digit nanoliters per minute up to several hundred milliliters per minute, and a suitable electrical interface for almost any environment:
- SCC1-USB sensor cable for laboratory and desktop use provides a plug-and-play connection to a PC for operation with Sensirion’s viewer software or user-built programs.
- SCC1-RS485 sensor cable for demanding industrial automation environments features a stable RS485 interface and includes advanced functionalities such as dispense volume totalizer, automatic dispense detection and data buffer for asynchronous read-out.
- SCC1-Analog sensor cable for simple and quick readings without programming or for integration into generic controller systems. In addition to a 0-10 V analog voltage output, the cable provides a configurable digital (high/low) output that can be programmed to act as a flow switch or as a pulse output.
The SLx liquid flow meters are the first choice for standalone applications in industrial automation systems, laboratory set-ups, bench-top testing, and technology evaluation. The robust housing (IP53 or higher) protects them from dust or accidental spills.
