The Josette: Improving the measurement accuracy of discharged flow



The wider the weir crest, the higher the flowrate generated by low heads, which generate high uncertainties.


The 3D EAU solution

The Josette increases the water head for low discharges, allowing for more accurate measurement.

The Josette is a rounded V-shaped weir.  The head-discharge relationship was validated numerically and experimentally as shown in the video below.
