Ellenex PLM2-N: Submersible Miniature Level Sensor for Underground Water bore monitoring. Modern LPWAN technologies ensure longevity and compatibility with future infrastructure. The choice between cellular (PLM2-N) and LoRaWAN (PLM2-L) depends on the specific operational requirements and existing infrastructure.

Groundwater is a vital but depleting resource. Monitoring 2-inch wells has long been a challenge due to size and cost constraints. Ellenex introduces the PLM2 series—the 'Tiny Tech Titan.' With a 15.8mm sensor head, it fits narrow wells perfectly. Available in PLM2-N and PLM2-L, it offers 40% lower costs than alternatives. From aquifers in Germany to sites in Canada, these sensors deliver real-time data for precision water stewardship.

As water scarcity and climate variability intensify across Europe, particularly in Germany where nearly 70% of drinking water depends on groundwater, the need for intelligent water resource management has never been more critical. This case study explores how advanced Industrial IoT (IIoT) technologies are transforming groundwater level monitoring in underground bores, enabling municipalities and water authorities to shift from reactive operations to data-driven, predictive m
