Watertight and energy-autonomous devices specifically designed to render water networks connected and smart

The SOFREL LX product range consists of Data Loggers specifically designed for water networks. Watertight, operational for up to 10 years thanks to their high-capacity lithium battery, fitted with a high-performance 2G/3G antenna, the LX Data Loggers are compatible with all instruments used in water networks.

Very simple to set up and easy to use thanks to the SOFREL PCWin2 and WEB LS software, the LX Data Loggers are also able to communicate with all commercially available SCADA systems and with the major third party water operator applications.

A robust and sustaibable design capable of afdapting to demanding environements

The constraints associated with water networks have been clearly defined:

  • Subterranean device installation
  • Risk of prolonged flooding
  • Weak reception of radio waves
  • Isolated and difficult-to-reach sites

In response to these constraints, LACROIX Sofrel proposes a range of Data Loggers widely acknowledged for its robustness and reliability.

Thanks to their high-quality electronic and mechanical design, these devices are provided with a 3-year warranty.

SOFREL LX Data Loggerskey strenghts

SOFREL LS and LT Data Loggers have won prizes at international trade fairs and been widely adopted by water network operators all over the world.
Since the range was first launched, specific features and uses connected to water management have been introduced to enhance the SOFREL data logger offer. Currently, hundreds of thousands of devices deployed on isolated sites and subject to severe conditions in the field (humidity, absence of electricity, intermittent GSM reception, etc.) supply daily data used to monitor and react to water network performance levels.

Robust and innovative products in the IIoT (Industrial Internet of Things) market, SOFREL LX models provide numerous benefits.

Reinforced IP68 watertightness

Most often placed in manholes, the SOFREL LX data logger is frequently subjected to submersion phenomena. Thanks to its closure system and its military-style connector, the IoT LX enjoys reinforced IP68 classification, enabling it to function even when the manhole is flooded.

While strictly watertight, the user can open their data logger on site (no factory return required) to access the SIM card and battery,
With its ring and locking system, a simple “twist of the hand” is all it takes to close up your equipment and make it entirely watertight,

The battery and energy management system offer up to 12 years of power

Battery lithium powered


Depending on the model and its use, the high-capacity battery in LX data loggers provides power for up to 12 years.

With its low energy consumption, the LX can reduce maintenance costs for your fleet (fewer battery replacement operations).

Furthermore, it is possible to anticipate expiry of the battery by  analysing the remaining energy. As such, replacing the battery takes just a few minutes (no factory return required), without loss of use of the product.

Simplified start-up

The device is configured wirelessly via the PC’s Bluetooth connection. This makes it possible to intervene in complete safety close to the manhole.

The operator is guided by the SOFTOOLS configuration software. This software is characterised by its highly intuitive visual aspect. It takes just a few minutes to get your data logger up and running.

With the SOFREL application, it will always be possible to remotely modify the configuration of your data logger.WEB LS
