ATIOMETRIC
V-Notch Angle Weir
(Non-BS 3680)
If the flow calculation is to be
ratiometric P702 = 2
the flow will be
calculated using the formula: q= q
cal
(h+kh/h
cal
+kh)
2.5
Where: q = flowrate
q
cal
=
flowrate at maximum head P705
h = head
kh = compensated head
Universal Calculations
Point of Measurement
The transducer must be above the
maximum head P704
by at least the near
blanking distance P107
.
For all
Universal
calculation applications, the point at which the head is
measured should be chosen such that the surface of the liquid is not effected
by turbulence.

Universal Head Vs Flow
If the flow calculation is to be
absolute
P702
=
1
the flow will be calculated
using the formula: q = q(h)
Where: q
= flowrate
q(h) = flowrate for head
The desired number of
Breakpoints
,
(
P730 - P793
) are to be entered in
pairs in values of
head
and corresponding
flow
. (Minimum of 2 pairs of
Breakpoints is required).
