UB-Flow powered by solar panels
As part of the ANR SSHEAR (« Sols, Structures et Hydraulique : Expertise et Recherche Appliquée ») project, the IFSTTAR laboratory leads a study about scouring risks at a train bridge. To collect data on the long term, Ubertone provided a set of sensors powered by battery and solar panels.
A camera takes a picture two times a day, a levelmeter measures every 5th minute, and a UB-Flow does several profile measurements every 5 minutes too.
The UB-Flow is installed downlooking on a floating board and observes the vertical over 1.5m depth.
All the collected data are made available on cloud.ubertone.eu and can be accessed with a personal account by the users. The camera pictures may be visualised on the cloud or downloaded like every recorded data.
Depending on the sunshine and the battery level, the charge controller may cut the power for camera and modem. Only the UB-Flow continues measuring independently. It stops automatically when battery voltage is too weak and starts measuring again as soon as the voltage is high enough. When the battery is full, the UB-Flow can measure 4 days without sun.
