Broad Crested Weir

DESCRIPTION:

Broad Crested Weir (FM-1361.10)

Contains a cuboid shaped weir body with a sharp edge. Two additional elements can be fixed at the weir body to create rounded edges. Free and submerged overfall can be clearly demonstrated. The effect of the sharp-edged or rounded weir crest on the nappe is easily observable.
