Leopold Lagco Flume
Application information
•
Designed to be installed directly into pipelines and manholes
•
Leopold Lagco may be classed as a rectangular Palmer-Bowlus flume
•
Sized by pipe (sewer) diameter
•
For rated flows under free flow conditions, the head is measured at a point
upstream referenced to the beginning of the converging section. Refer to the
following table:
