What is BS 3680-4I - V-shaped broad crested weirs about?
BS 3680-4I is an International Standard that discusses the uses of V-shaped broad crested weirs.
BS 3680-4I specifies a method for the measurement of subcritical flow in small rivers and artificial channels using V-shaped broad-crested weirs. BS 3680-4I describes the advantages of V-shaped broad crested weirs.
Who is BS 3680-4I - V-shaped broad crested weirs for?
BS 3680-4I on V-shaped broad crested weirs is useful for:
- Manufacturers and designers of V-shaped broad crested weirs
- Manufacturers and designers of flowmeters
- Testing laboratories
- Water resource engineers
- Hydrologists
- Quality control and testing authorities
- Regulatory authorities
Why should you use BS 3680-4I - V-shaped broad crested weirs?
The V-shaped broad-crested weir has a V-shaped cross-section with a horizontal vertex line. It is widely used for measuring the liquid flow in open channels and in small rivers.
BS 3680-4I lays down the technicalities for V-shaped broad crested weirs, that use a technique to calculate the subcritical flow in the open artificial channels and small rivers. It provides you with the features that help you in selecting the site of the weir and gives you detailed information about the installation conditions such as approach channel, measuring structure etc. BS 3680-4I covers the requirements for maintenance of the measuring structure and the approach channel which helps you in ensuring continuous and accurate measures. BS 3680-4I presents you with working of V-shaped broad-crested weirs and additionally gives you requirements such as measuring the head and determining the head-gauge datum for weirs with a movable crest. BS 3680-4I also contributes to rectifying the errors in flow measurement.
BS 3680-4I is an effective step for measuring the liquid flow in open channels through V-shaped broad crested weirs.
