RATIOMETRIC<br />
If the flow calculation is to be ratiometric P702 = 2 the flow will be<br />
calculated using the formula: q = q cal (h/h cal ) X<br />
Where: q = flowrate<br />
q cal = flowrate at maximum head (705)<br />
h = head<br />
h cal = maximum head (P704)<br />
x = exponent (determined as in absolute calculation above)<br />
