V-notch weir หรือ ฝายร่องวี เป็นอุปกรณ์วัดการไหลของน้ำในช่องเปิด (Open Channel) ที่ทำจากแผ่นบาง โดยมีร่องหรือช่องรูปตัว V เจาะไว้เพื่อให้น้ำไหลผ่าน ซึ่งการวัดระดับน้ำเหนือร่อง V จะช่วยให้คำนวณอัตราการไหลของน้ำได้อย่างแม่นยำ โดยเฉพาะอย่างยิ่งสำหรับการวัดอัตราการไหลต่ำ สนใจติวสอบนายช่างวิศวกรชลประทานพิมพ์ 01 | นายช่างดอย4.0
