PULSAR MEASUREMENT

BS3680 Rectangular Broad Crested Weir

Point of Measurement

The transducer must be above the

maximum head P704

by at least the

near

blanking distance P107

The head is measured at a point 3 to 4

times

the

maximum head

upstream

from the weir crest, to ensure the surface of the liquid is not affected by
turbulence or drawdown.

Rectangular Broad Crested Weir Calculations

Calculations
Absolute

If the flow calculation is to be

absolute

P702

the flow will be calculated

using the formula: q = (2/3)

1.5

b(gh

)

0.5

Where:
q = flowrate

discharge coefficient

calculated by UltraTWIN

P723

b = approach width

P710

g = gravitational acceleration (nominal value = 980.66 cm/s

)

h = head
