Flood Warning

Flood warning systems built into hydrological stations are used to notify local emergency authorities in the case of a flood event.

OTT water level sensors and continuous flow sensors, paired with telemetry technology and OTT Hydrosystems are able to measure, collect, and transmit water level and velocity data in real-time to determine the peak level or flow during flood events, and alert local water and emergency authorities if a certain threshold is breached.
