For decades, precise river gauging meant one thing: complex, costly, and disruptive cable installations across the water. That era is over. NIVUS introduces Wireless Transit Time technology, a revolutionary, cableless measuring solution for real-time surface water flow monitoring.

The High Cost of Old Technology

Traditional methods of river flow measurement are holding you back. They require extensive civil works, such as running armored cables in trenches across riverbeds. This approach is not only incredibly expensive (often several 100K €), but it also limits your options. Measurement sites are chosen based on convenience, like an existing bridge, not on what is best from a hydrometric standpoint. This compromise limits data quality and inflates budgets.

The Future is Cableless: Wireless Transit Time Measurement

Our Wireless Transit Time system provides the high-quality, real-time data you need, without the drawbacks of physical cables across the river. By using GPS for ultra-precise time synchronization, our sensors communicate wirelessly across the river, delivering accurate time-of-flight flow velocity measurements.

This completely eliminates the need for disruptive and costly river crossings. Now, you can establish a highly accurate river gauge at the hydraulically perfect location, not just the most convenient one. This innovation opens up new possibilities for monitoring large river systems and remote locations that were previously inaccessible.

Unlock Unprecedented Advantages

Drastic Cost Savings
- Eliminate the immense expense of civil works and underwater cable installation. The installation cost and maintenance regimes are substantially reduced.
Ultimate Site Flexibility
- Choose measurement sites based purely on hydraulic considerations, not existing infrastructure. Install a precise river gauge wherever you need it most.
Access Unmeasurable Sites
- Large, remote, or protected river systems are now accessible, providing critical real-time flow data for better decision-making.
Superior Accuracy
- With up to 32 measurement paths, our system delivers highly precise and reliable river flow monitoring data, compliant with ISO 6416.
Minimal Environmental Impact
- Avoid trenching and other disruptive construction in sensitive river ecosystems. Our system requires minimal intervention and reduced material usage.
Fully Self-Sufficient
- Designed for remote deployment, the system can be powered by solar panels and batteries, ensuring continuous monitoring without reliance on the grid.
