Understanding the Challenge
That was the question from one of our customers, who needed to understand the volume of water passing through a square water channel on their property. The goal was simple: calculate the total water flow in cubic metres per hour.
The method is rooted in fundamental hydrodynamics. With just three parameters—water temperature, channel width, and water depth—a real-time flow rate can be calculated using a modified form of the Manning equation. This equation is adapted for open-channel flow in rectangular conduits. To make this accessible, we embedded the formula directly into our IoT platform. This allows the user to input channel width once and then get live flow estimates based on sensor data.
Robust Hardware in the Field
To make it happen, we provided an AKKR8 unit in an IP65-rated enclosure. This design is perfect for year-round outdoor use in harsh environments. The system was configured with:
A 4–20 mA analog level sensor to measure water depth.
An external temperature probe to track water temperature.
The device is driven by mains power with a built-in battery backup, ensuring uninterrupted operation even during power outages.
The AKKR8 gateway transmits data over the mobile network. It connects seamlessly to our cloud platform, where real-time readings are turned into actionable insights—cubic metres per hour, visualised, logged, and exportable.
Why This Matters
Across the globe, countless small streams and channels flow quietly—until they don’t. Real-time measurement helps detect anomalies, observe seasonal changes, and plan for heavy rainfall. For rural areas or remote sites, it’s a low-cost and low-maintenance way to gain control over local water flows—without complex infrastructure.
A Ready-to-Use Solution
By combining basic hydrology with smart IoT, the customer gained a plug-and-play solution that delivers flow measurements with high reliability. Because it’s based on standard sensors and an open platform, the same setup can be scaled to other locations. It can be configured for other channel geometries or integrated with weather forecasts and alarm logic. If mains power is not available, the device can be equipped with a solar panel as well. From passive observation to proactive planning—one stream at a time.
The Future of Water Management
As we look ahead, the integration of IoT in water management will become increasingly vital. The ability to monitor water flow in real-time can help businesses and municipalities make informed decisions. It can also enhance disaster preparedness and response strategies.
Imagine a future where every small stream is monitored, where data is collected and analysed continuously. This vision is not just a dream; it’s becoming a reality. With the right tools and technology, we can revolutionize how we manage our water resources.
Conclusion
In conclusion, measuring water flow with IoT is not just about technology. It’s about creating solutions that empower us to manage our resources better. By leveraging smart solutions, we can ensure that we are prepared for whatever climate challenges come our way.
