Sensirion's SLI, SLS, and SLG series liquid flow meters all feature a robust IP53 or higher protected housing and a 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. The SLI, SLS, and SLG series 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 protects them from dust or accidental spills.
SLI Series
The SLI liquid flow meter enables fast, non-invasive measurements of very low liquid flow in the µl/min- to ml/min-range. Excellent chemical resistance is ensured; the flow path of the SLI liquid flow meter is formed by a simple, straight glass capillary. The fourth-generation MEMS sensors combine a thermal high precision sensor element with amplification circuits and digital intelligence for linearization and temperature compensation on one single microchip, the product’s core element.

SLS Series
The SLS-1500 liquid flow meter enables precise, non-invasive measurements of dynamic liquid flow rates up to 40 ml/min bidirectionally. 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.
