Flow measurement by notched weir
WebUse a V Notch Weir to Measure Open Channel Flow Rate May 12th, 2024 - The v notch weir is widely used to measure open channel flow rate It is especially good for measuring a low flow rate because the area of flow through the v notch becomes quite small while the head over the v notch is still a measurable value Drilling Engineering Association WebThe V-Notch (triangular) Weirs are typically installed in open channels such as streams to determine discharge (flow rate). The main component is a cylindrical weight suspended from a vibrating wire force transducer. As …
