The module enables to evaluate the characteristics of flow over weirs with different shapes. It consists of 4 weir elements that an be placed at the end of the open channel of the hydraulic bench. The water is feed in the channel through a dispenser in order to reduce liquid turbulence and ensuring a more regular flow. The measurement of level inside the channel is done through a depth gauge that is dropped onto the free surface of water. The used weirs are fastened to the holder mounted at the end of the channel by screws.
