An integrated offering covering the small water cycle for the monitoring, operation, and performance management of water networks. Integrated platforms for the centralization and supervision of water networks.

SOFREL S4W End to End users RTUs for water network management

User-friendly Remote Terminal Units

Dedicated to water network management, SOFREL’s local Remote Terminal Units integrate communication modems and rely on their specialized ‘Water’ functions to monitor sites 24/7, alert in case of anomalies, manage, and manage and automate technical facilities.

With SOFREL telemetry devices, contract operators can remotely control their facilities, act on motors, pumps, or valves, and even automate their facilities’ processes.


SOFREL Water data logger installation

4G LPWAN and 5G Ready data Loggers

SOFREL IoT data loggers have been specially designed for the remote monitoring of underground hydraulic facilities which are isolated and have no electricity (metering manholes, sewer overflows, etc.).

They perform calculations, save and regularly log data from the facilities and communicate it via 4G to the SCADA central stations.
They directly contribute to the performance of drinking water networks by quickly detecting leaking sectors. 

For waste water, SOFREL data loggers contribute to network self-monitoring and continuous diagnostics.


SOFREL Water level sensors

A range of sensors for level, pressure, and quality measurement

LACROIX offers a full range of sensors for measuring height, pressure, quality, and more. Robust and precise, they are specifically designed to provide the best performance for installations equipped with SOFREL local units or data loggers.


Integrated platforms for the centralization and supervision of water networks.

Our LX SCADA, LX CONNECT, and WEB LS solutions are dedicated to the centralization and supervision of water networks.

The LX SCADA supervisor enables efficient and optimized management through remote monitoring of installations and real-time alerts.

The LX CONNECT platform orchestrates cybersecurity, centralizes the management of equipment and users, and offers a 360° view of the deployed fleet.

The WEB LS platform allows for the simple and efficient exploitation of data from SOFREL DL4W data loggers.

Together, these solutions provide smooth, secure, and intuitive management for the remote operation of water networks.


Gateways and Communication Servers

Managing a telemanagement network involves centralizing all information from different sites. Our data communication solutions serve as gateways between field equipment and supervisory or hypervision systems.

We offer a complete ecosystem that includes gateways and communication servers to improve the reliability of communications.
