Calculations
ABSOLUTE
If the flow calculation is to be absolute P702 = 1 the flow will be calculated
using the formula: q = Kh
x
.
Where: q = flowrate
K = constant factor (P718)
h = head
X
= exponent (P717)
RATIOMETRIC
If the flow calculation is to be ratiometric P702 = 2 the flow will be
calculated using the formula: q= q
cal
(h/h
cal
)
X
Where: q = flowrate
q
cal
= flowrate at maximum head (705)
h = head
h
cal
= maximum head (P704)
x = exponent (P717)
