OTT HydroMet Launches the OTT Flood Monitoring System 

Kempten, Germany – April 22, 2025 – OTT HydroMet, a global leader in environmental monitoring and weather measurement, is expanding its hydrological and meteorological offerings with the launch of the OTT Flood Monitoring System, a cutting-edge flood monitoring and stream gauging solution. This hydrology-tailored system seamlessly integrates the OTT SensorLink 1000 IoT device with the next-generation OTT RLS 500 radar water level sensor, providing customers with the high flexibility and operational efficiency needed for swift and confident decision-making when both preparing for and navigating the increasing severity of flooding events. 

Comprised of a radar level sensor, datalogger, modem and power supply, the OTT Flood Monitoring System leverages the strengths of OTT HydroMet’s existing technologies. It offers reliable, easy-to-install, and low-maintenance water level measurements without requiring extensive technical knowledge through key features including:  

• An FMCW radar that measures water levels with high accuracy (±2 mm) and a range of up to 30 meters 

• IP67 housing to ensure reliable performance in all weather conditions  

• Timely notifications that enable proactive actions if water levels exceed thresholds 

• The ability to configure remotely and operate the system via smartphone or PC using Bluetooth Low Energy (BLE) 

"The OTT Flood Monitoring System marks a significant milestone in our commitment to equipping community leaders and environmental stewards with the tools they need to observe and adapt to our changing world,” said Hannes Tietz, Global Product Manager at OTT HydroMet. “Being able to detect changes in the water table to better assess the impact of drought or climate change, as well as water availability and use over time through our new system helps ensure communities remain safe and can thrive.”   

The OTT Flood Monitoring System is designed for flood monitoring, flood warning, short and long-term continuous monitoring, and monitoring locations requiring data in near real-time. The system can be used in fresh, brackish or saltwater environments and deployed in urban to remote locations with mobile signal, bridges and rain retention basins.
