Non-intrusive measurement method using only one sensor (camera)
Data storage and remote transmission of measurement data and images
Intelligent alarm management
Benefits
Simple installation: The weatherproof IP-camera and the sensor controlled infrared beamer can be mounted easily on e.g. a water gauge station, a mast, concrete constructions or a bridge. The process unit can be housed in a water gauge station or in a protective case. Elaborate and expensive installations in the water are no longer required.
No flow tracers required: A special feature of the measuring system is that no flow tracers need to be added for flow velocity detection. The DischargeKeeper operates on visible moving surface structures, although naturally occurring floating objects on the water surface (e.g. leaves) enhance the measurement signal.
Representative measurement: Unlike other non-intrusive sensor types (such as radar), the Discharge-Keeper delivers a flow rate measurement (profiling) on the entire surface of the image section. This provides a representative and spatially resolved flow velocity detection.
Non-intrusive: The optical measuring system DischargeKeeper does not come into contact with the measured medium. A damage of the equipment as a result of siltation, vegetation growth etc. is excluded. Therefore the technology is practically maintenance free.
On-site evaluation: All DischargeKeeper measurement parameters (water level, velocity profile, and discharge) are collected and processed locally on the measuring site, almost instantaneously.
