Triangular Profile Weir
 Flumes & Weirs

FlowMarque Standard triangular profile weirs conform to BS ISO 4360.

This versatile, high-capacity structure has a sharp crest with a 2:1 approach slope that allows suspended solids and bed-load solids to be carried over the weir.

Weirs up to 1.2m width are prefabricated.   Larger weirs are cast in concrete from steel formwork and then craned into position.

FMcert calibrated variants of the Standard weirs are available for flow measurements down to 1 l/s.
