The measurement task: online measurement of water level and velocity of flow with subsequent discharge calculation according to the velocity-index-method. Besides, all data should be stored and made available in real-time for the planning and control tasks of the StAUN and of the water and shipping authority. For this purpose, a remote data transmission system had to be installed. Further, the customer required the possibility of remote maintenance of the measurement systems via analogue line.
- OTT SLD 2.0 MHz Side-Looking-Doppler-Sensor for measurement of local velocity of flow (index velocity)
- OTT CBS – compact bubble sensor for long term-stable water level measurement
- Station manager OTT LogoSens2 for monitoring and storage of measured data, calculation of discharge quantities and control of remote data transmission via analogue modem (mainlines available).
The new measurement site, equipped with state-of-the-art OTT instruments from now on provides discharge data around-the-clock. The measurement instruments have been and are working without any failure since summer 2009.
