Product Description

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.

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.

Simple, Robust and Highly Accurate

The principle is as powerful as it is simple. Ultrasonic sensors are placed on opposite banks of the river. They send signals back and forth, and the system measures the 'time of flight'. The difference in time between the upstream and downstream signals allows for a precise calculation of the water's velocity. By using multiple paths (up to 32), we create a detailed velocity profile for exceptional accuracy. A master and slave unit, synchronized via GPS, manage the communication wirelessly, making the entire system robust and without the need of cables across the river.

The System

The NivuFlow 650 W measuring system is ISO 6416, IEC 60041 and ISO 748 compliant and has been specially developed for flow measurement in canals and surface waters. Up to 32 measurement paths ensure maximum accuracy. A selection of sensor designs and installation accessories offers a wide range of options for optimised measurement at every measurement point.
