Dekimo Goes contributed to the development of the industrialised Multiflexmeter v4, an open-source platform designed for automated groundwater monitoring across large-scale networks.
Following a successful pilot with analogue pressure sensors in 2022, the Province of Zeeland decided to scale up its monitoring network, covering more than 600 locations. The redesign and industrialisation of the system was assigned to Dekimo Goes, resulting in a compact and modular solution that can be installed directly on existing monitoring wells.
The Multiflexmeter is built around a baseboard with plug-in sensor modules, allowing flexibility for different applications. Two types of modules are currently available, supporting Modbus RS485 and OneWire communication, with each module capable of handling 2 sensors. An extension board enables configurations with up to 12 sensors in a single system.
The system is optimised for long-term field deployment with minimal maintenance. With a measurement interval of once per hour, it can operate for up to 10 years on a single battery. Data is transmitted via LoRaWAN and can be stored locally for extended periods in case of temporary connectivity loss. Configuration can be managed remotely, and the hardware is prepared for future firmware updates.
The solution is already deployed in more than 250 monitoring wells, where data is automatically collected and integrated into the central groundwater database.
In addition to its industrial use, the Multiflexmeter is made available as open source, enabling further use in education, research and other applications.
