BS3680 Flumes
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 effected by turbulence. (See
DRWG 6)
