The Josette : Reliability of self-monitoring of discharged flows
The longer the thresholds are, the more significant the flows generated by the low overtopping blades. The uncertainty in assessing the volume spilled is then incompatible with reliable measurement.
The 3D EAU solution
The Josette, a rounded V-shaped sill, makes the measurement of the tilting blade more reliable. The conversion from height to flow is adapted to self-monitoring objectives. The height/flow rate relationship used is digitally and experimentally validated as shown in the video below.
