Bench-Top Weir Apparatus with Rectangular and V-Notch Plates

台式堰流实验仪(矩形堰与三角堰板)

Irrigation engineers measure canal flow with weirs, so students must calibrate one themselves. This set adds a baffled approach channel and stainless rectangular 30 mm and 90° V-notch plates to a hydraulics bench. A 0–150 mm hook and point gauge with 0.1 mm vernier reads head up to about 100 mm, for flows to 1.2 L/s.
