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.
