Water monitoring in reservoirs requires continuous depth profiles – previously only possible manually from boats. This profiler winch fully automates the process: Up to 8 times daily, an OTT HydroLab 7 probe captures oxygen, temperature, pH value, and algae concentration across the entire water column. The measurement data flows directly into the central control system of the Aabach reservoir, which supplies drinking water to 200,000 residents. The result: Comprehensive data monitoring for optimal operation of the deep-water aeration system – without manual boat trips.

Technologies Used:

• Siemens S7-1200 PLC
• OTT HydroLab 7 multiparameter probe
• OTT netDL 1000 data logger
• Unigate MB protocol converter
• Custom winch design (100m cable capacity)
