What is BS 3680-4F - Round nose horizontal broad-crested weirs about?
BS 3680-4F is an International Standard that discusses the measurement of liquid flow in open channels .
BS 3680-4F deals with the measurement of flow in rivers and artificial channels under steady flow conditions using round-nose horizontal broad-crested weirs.
The flow conditions considered in BS 3680-4F are limited to steady flows which are uniquely dependent on the upstream head.
BS 3680-4F describes round-nose horizontal broad-crested weirs that have a good discharge range and their modular limit and are appropriate for use in small- and medium-sized installations. Round-nose horizontal broad-crested weirs are particularly robust and insensitive to minor damage.
