LPWAN SOLUTIONS
Solution
The Remote River Flood Monitoring Solution provides near-real-time water surface level, derived flow calculations, historical flood trends, and configurable threshold alerts for remote rivers, streams, and floodplains—eliminating the expense, safety risks, and operational complexity of traditional wired river gauging infrastructure. Engineered for rapid field deployment above open waterways, the system comes pre-configured out of the box to automatically stream encrypted sensor telemetry directly to the Ellenex Software Platform.
This IoT-driven environmental monitoring solution offers several key advantages:
Zero-Touch Field Deployment: Delivered fully pre-programmed for the Ellenex Platform. Enables immediate, non-contact installation over bridges or mounting arms with zero local software programming, driver downloads, or complex field provisioning.

Our Remote River Flood Monitoring Solution provides a comprehensive approach to efficient water resource management and early flood warning. By leveraging cutting-edge 80 GHz non-contact radar level sensors, municipalities, catchments, and industrial facilities can track, control, and optimize their flood monitoring systems in real time. The result is a future-proof solution that not only addresses current hydrological challenges but also adapts to changing climate demands, ultimately protecting our infrastructure, public safety, and natural ecosystems.
Connecting remote rivers, streams, and floodplains to a central digital network transforms static, unmonitored waterways into an intelligent infrastructure monitoring network. By feeding continuous sensor data directly to a cloud platform, emergency managers and civil engineers gain complete control over every watercourse in their region while eliminating blind spots during critical storm events.
Asset Visibility
Continuous telemetry from 80 GHz non-contact radar sensors provides total operational oversight across every remote waterway through a single, centralized dashboard. Instead of relying on manual, periodic physical check-ups that leave long gaps between readings and put personnel in harm's way during severe weather, teams receive live updates on river stage levels, derived discharge rates, and rate-of-rise metrics. Automated high-water alerts immediately flag rapid water level increases, allowing emergency teams to visualize rising floodwaters instantly and coordinate local emergency responses before floodwaters breach banks.
Resilient Operation
Continuous telemetry from IP68-rated non-contact radar hardware guarantees complete operational resilience across vulnerable floodplains through a single, centralized dashboard. Designed to operate entirely out of the water column mounted above bridges or gantries, the radar system avoids damage from submerged debris, mud siltation, or turbulent flood currents during severe inundation events. Powered by an internal long-life battery and enclosed in a UV-stabilized, IP68 housing, the system remains completely functional during severe storms and power grid blackouts—enabling authorities to maintain live telemetry feeds, automate flood gate controls, and protect critical downstream assets without interruption.

Industrial Outdoor LoRaWAN Gateway Specifications
For customers deploying the LoRaWAN package, the high-performance industrial gateway provides complete self-managed coverage. It is pre-configured to forward packet data to the Ellenex Platform.
System Architecture
The integrated Solution telemetry platform is designed around a dual-LPWAN (Low Power Wide Area Network) hardware architecture, giving operators the flexibility to deploy either LoRaWAN or cellular-based (supporting NB-IoT and LTE Cat M1) network configurations depending on local infrastructure and regional topology. Both communication technologies represent the cutting edge of industrial IoT, designed to penetrate challenging physical barriers and achieve multi-kilo meter propagation distances while maintaining extremely low electrical current draws.
The Ellenex telemetry pipeline follows a streamlined 4-step end-to-end data flow designed to give customers total choice over their network infrastructure and software platform:
-
Sensor: The single Ellenex battery-powered field device directly measures physical parameters, digitizes analog signals, applies factory calibration parameters, packages telemetry into AES-128 encrypted payloads, and manages low-power sleep modes within a unified unit. Learn More:

Frequently Asked Questions
How does 80 GHz non-contact radar technology improve river level measurements compared to submerged sensors?
The Remote River Flood Monitoring Solution uses 80 GHz millimeter-wave non-contact radar sensing to measure the distance to the water surface without ever touching the fluid. Because the sensor is suspended above the river on bridges, culverts, or mounting posts, it is completely immune to physical hazards like bio-fouling, sediment build-up, debris impact, or rapid current turbulence that frequently damage submerged pressure sensors during flash floods. This ensures continuous, pinpoint accuracy and eliminates the need for sensor cleaning or un-clogging maintenance visits.
How are false readings from floating debris, waves, or riverbed vegetation filtered out?
The 80 GHz radar technology features a focused beam angle and advanced signal processing algorithms that automatically filter out surface interference, such as wind-driven ripples, floating logs, turbulent foam, and overhanging vegetation. Raw millimeter-wave echoes are processed on-device to deliver a stable, true surface height measurement to the Ellenex Software Platform. This ensures that emergency alerts reflect actual hydraulic stage rises rather than temporary surface clutter.
Can the system automatically increase its reporting rate during a flash flood event?
Yes, through the Ellenex Software Platform, users can configure dynamic transmission parameters based on rate-of-rise thresholds. Under normal baseline conditions, the unit transmits encrypted level readings at extended intervals to maximize battery efficiency. However, if the sensor detects a rapid, anomalous rise in water level during a sudden rainstorm, the firmware automatically accelerates its sampling and transmission frequency to provide near-real-time stage updates. This gives emergency response teams crucial early warnings as flash floods develop.
How is the radar unit mounted in remote areas without grid power or existing structures?
The solution is designed for off-grid deployment anywhere along a river basin. Because the transmitter operates on an internal 3.6V replaceable Lithium battery for up to 10 years, it requires no external solar panels or mains wiring. The compact, IP68 UV-protected enclosure and radar assembly can be easily clamped onto bridge railings, overhanging gantries, or dedicated roadside posts using standard mounting brackets, enabling complete installation in under 10 minutes.
What wireless connectivity options are available for remote river basins with weak signal coverage?
To overcome topographical challenges in deep river valleys or remote catchments, the solution supports dual LPWAN architectures. In regions with established public cellular infrastructure, the NB-IoT / LTE-M variant (-N) utilizes +20 dB link budget enhancements to establish reliable direct-to-tower connectivity. In completely isolated, off-grid river valleys lacking cellular networks, the LoRaWAN variant (-L) uses sub-GHz radio frequencies to relay data over several kilometers to an Ellenex Outdoor Gateway, which routes the telemetry seamlessly to the Ellenex Software Platform.
How can early flood warning alerts be shared with civil defense or public safety platforms?
While the system provides real-time dashboards and automated SMS/email alerts natively through the Ellenex Software Platform, it is built on an open, API-first architecture. Telemetry streams can be pushed directly to municipal emergency management systems, civil defense software, or public warning portals using Ellenex Open APIs, Webhooks, or MQTT streams. This allows automated flood triggers to activate local sirens, update digital road signs, or inform regional emergency dispatch systems instantly.
