Measuring weir

A measuring weir was set up at „Klausen- Leopoldsdorf“ site for high resolution recording of carbon (C) and nitrogen (N) fluxes and futhermore for the permanent observing of water quality. Under an existing road, a measuring tube was installed. A water level sensor (OTT) was mounted inside the tube to gain data about the anually flow rates. In addtion, a multifunction spectrolyzer (S:CAN) for measuring NO3-N, TOC, DOC, water temperature and electrical conductivity installed. A water probe sampler (OTT) was also installed near the measuring weir. This samlper enables automated sampling for further labratory analyzes.
