System designed and tested by the I-Cube laboratory of ENGEES and IJINUS within the framework of the OSRAI project. DESCRIPTION INFORMATION DOWNLOAD Presentation and principles of the OSRAI Flow system The Osrai Flow system is based on the principle of the flow contraction by an “obstacle” in order to guarantee a hydraulic law between the flow and the height of water upstream. The "semi-circular" shape (view from the top) and on one side of the cunette has been selected to limit the risk of clogging and to be able to be installed in an existing manhole. The size of the obstacle also makes it possible to have reliable flows for upstream slopes of up to 4%. An Ijinus probe makes it possible, with established laws, to provide the flow rates and therefore the volumes transited. Several dimensions of the obstacle are available depending on the size of the collector, the slope and the minimum and maximum flow rates. IJINUS LNU06V3 ultrasonic level sensors integrate the flow laws of the Osrai Flow device Quick installation, local radio connection Integrated conversion tables Water sampler control Sensor with or without modem for sending data remotely Lithium battery, long duration Development of the laws and their characteristics As the laws of this form of contraction did not exist, for each device configuration (pipe diameter, slope, semi-circular diameter of the obstacle, etc.), 3D models were used. carried out by the I-Cube laboratory of ENGEES in order to establish the relationship between flow rate and height. The values given here are only valid for vertical obstacles and up to a maximum height equal to the diameter of the pipe. These laws are coded in the Avelour operating software and therefore available in the Ijinus water height measurement sensors.
