The SOFREL DL4W range consists in LS / LT, OpenSensor & NEO data loggers specifically designed for drinking water and wastewater networks. Watertight, operational for up to 10 years thanks to their high-capacity lithium battery, fitted with a modem and a high-performance 2G/4G antenna, the 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 Data Loggers are also able to communicate with all commercially available SCADA systems and with the major third party water operator applications.
The constraints associated with water networks have been clearly defined:
In response to these constraints, LACROIX 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 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 data loggers models provide numerous benefits.
Most often placed in manholes, the SOFREL data logger is frequently subjected to submersion phenomena. Thanks to its closure system and its military-style connector, it enjoys reinforced IP68 classification (certified 30 days under 4m), 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,
Depending on the model and its use, the high-capacity internal battery provides power for up to 10 years.
With its low energy consumption, the data logger 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.
The OpenSensor High Power model, in addition to its high capacity battery, has an EPS (External Power Supply) connection for powering the equipment from an external source (battery, mains, solar panel, microturbine…). This model is particularly suitable for the RS485 connection and the power supply of the most energy consuming sensors.
The advantages of 4G M2M, NB-IoT and LTE-M communication are, firstly, to respond to the constraints of isolated and underground sites by ensuring the IP interoperability of equipment (plug & play).
In addition, the low latency and deep indoor nature of these telecommunication technologies make SOFREL DL4W or NEO data loggers ideal tools for monitoring networks in all circumstances.
They ensure the transmission and integrity of the data needed to analyse water systems and help operators make decisions in real time.
An M2M network optimised for Connected Objects (IoT) gives the SOFREL data loggers even greater autonomy.
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 WEB LS application, it will always be possible to remotely modify the configuration of your data logger.
Since its creation in 1971, LACROIX Sofrel has specialized in the field of teletransmissions and in particular wireless communication technologies. A company that is now at the forefront of the field and thanks to strong investments in R&D, LACROIX Sofrel has designed data loggers incorporating (not for NEO model) a very high-performance 2G/4G antenna:
In case of high signal attenuation in the manhole, the FLEX version allows you to use either the internal antenna or an external antenna. This version allows to adapt to all field situations and saves time during the implementation of the product.
Also during installation, the data logger offers functions to test the signal reception level in order to set up the data logger in an optimal way.
