Application information
● Sized by pipe diameter D
● Flume relief is trapezoidal
● Designed to install directly into pipelines and manholes
● Head is referenced to bottom of the throat, not bottom of the pipe
● For rated flows under free flow conditions, the head is measured at a distance of D/2
upstream from the beginning of the converging section.
