Data Logger Sofrel LS-10

The SOFREL LS10 is an IoT data logger for remote meter reading, manufactured by LACROIX under the SOFREL brand, which specializes in remote management and monitoring solutions for water networks. It belongs to the SOFREL DL4W 4G LPWAN data logger range, designed for continuous monitoring of isolated sites and underground chambers in water networks, and is focused on the remote reading of major consumer meters.

The LS10 receives meter pulses through its digital input, stores up to 100,000 data points locally and calculates daily volumes, average flow, night flow, and daily minimum and maximum flows. Data is transmitted over 2G/4G M2M cellular networks (LTE-M and NB-IoT) to the utility's SCADA system via IP communication, with daily data logger synchronization; if the 4G LPWAN network is unavailable, it automatically switches to 2G to ensure data delivery. It can also send SMS alerts on status changes, threshold violations or sensor faults, depending on mobile operator activation.

Its enclosure features enhanced IP68 waterproofing, verified by an independent laboratory through 30-day immersion tests under 4 m (13.1 ft) of water, and a military-grade waterproof connector. It runs on a lithium battery and provides up to 10 years of battery life depending on the usage profile, so it can be installed in underground chambers without electrical power. Its screwless opening system eases field access to the SIM card and battery, and configuration is performed via Bluetooth.

The LS10 integrates with industrial supervisory systems and third-party applications used by water operators, and simplifies data use through the SOFREL WEB LS IoT platform. It also communicates in inter-station mode with SOFREL S500, S4W and AS remote telemetry units (RTUs), periodically or on events.
