Hydraulic management for surface waters

With the help of the NivuFlow Stick, VNF Strasbourg can quickly and easily calibrate the discharge measurement at its simple structures with Q/h relationship. The mobile measuring system NivuFlow Stick is designed for discharge measurements in surface waters. The measuring device appealed to VNF because of its light weight, simple operation, fast and complete recording of the flow profile and especially because of the time and cost savings due to the very short measuring times. Structures with challenging hydraulics, where the Q/h relationship cannot be applied, are equipped with NIVUS stationary transit time flowmeters at VNF Strasbourg. NivuFlow 650 multi-path measurements with rod or wedge sensors are used. The NivuFlow Stick and NivuFlow 650 duo, with their common interface, form a complete solution for flow measurement in natural environments. They meet the requirements of operators such as Voies Navigables de France and help them to perform their tasks efficiently.
