Sultan Flow Series

MANUAL

Draft 1.2, Mar 2009

BS3680 RECTANGULAR WEIR

In this example it is required to calculate to the flow through a BS3680 Rectangu

-

lar weir. Absolute calculation will be used. The flow rate is required to be displayed

in litres/minute and the totaliser is to record the flow in cubic metres.

The distance from the end of the transducer horn to zero flow is 1 metre and max

head is 0.4 metres, maximum flow.

Approach width (Dim”A”) = 0.5 m

Crest width (Dim “B”) = 0. m

Crest Height (Dim “C”) = 0. m
