Modern sensor technology at the historic Ettl Mill
The historic Ettl Mill in Grafenau, Lower Bavaria, boasts not only the carefully restored Zuppinger water wheel, but also a weir and fish ladder in the nearby Kleine Ohe. To keep a constant eye on the water level at these two critical points in the river, an efficient yet powerful IoT solution with sensor technology was to be installed.
Automatic water level measurement with alarm system working in harmony with nature.
The water level at the fish ladder of the 700-year-old Ettl mill was previously measured manually.Together with two partners, Thomas-Krenn has now developed a measuring station that automatically measures the water level, transmits it in real time and sounds an alarm if the water level is too high. The system is built to withstand harsh environmental influences, can transmit data over great distances and blends in well with the surrounding habitat.
