The head 0r water level above the crest or bottom of the v of this 90 degree v notch weir is accurately measured by a nivelco easytrek ultrasonic level transmitter.

V notch weir plate. We can even provide them as fabricated fiberglass weirs. The v notch weirs are are available in various angles and we typically fabricate them out of 14 or larger aluminum plate. The discharge tables here are for thin plate weirs in general. A v notch weir is simply a v notch in a plate that is placed so that it obstructs an open channel flow causing the water to flow over the v notch.

Openchannelflow fixed weir plates are used to accurately measure surface water and seepage flows. The name for a v notch weir is very descriptive as you can see in the picture and diagrams in the next couple of sections. Weirs are called sharp crested if their crests are constructed of thin metal plates and broad crested if they are made of wide timber or concrete. Triangular weirs are sharp crested thin plates with v shaped opening or notch.

If the notch plate is mounted on the supporting bulkhead such that the water does not contact or cling to the downstream weir plate or. Before relying on the full flow rates indicated on the tables below compare the depths indicated in the tables versus your application.

The triangular v notch and trapezoidal weirs are of order one. Available in v notch cipolletti rectangular and circular configurations. High order polynomial weirs are providing wider range of head discharge relationships and hence better control of the flow at outlets of lakes ponds and reservoirs.
