BS3680 Flumes (P700 = 2) 

Point of Measurement 

The transducer must be above the 

maximum head P704

 by at least the 

near 

blanking distance P107

.  

For a 

Rectangular 

and

 U-throated 

flume, the head is measured at 

3

 to 

4 

times

 the 

maximum head

 

upstream

 from the beginning of the 

converging 

section

, to ensure the surface of the liquid is not affected by turbulence.
