If P700 = 3 (BS 3680 Weir)
Select from the following options:
1 = Rectangular
2 = V-Notch Full 90 degree (full 90
o
)
3 = V-Notch 53 degree 8’ (half 90
o
)
4 = V-Notch 28 degree 4’ (quarter 90
o
)
5 = Broadcrested (Rectangular) Weir
If P700 = 5 (Special)
Select from the following options:
1 = Palmer-Bowlus Flume
2 = H-Flume
3 = V-Notch angle (other than BS3680)
If P700 = 6 (Universal)
Where the Primary Measuring device does not match any of the devices
contained in the above categories then a universal volume calculation can be
performed. A head Vs flow chart is used, to enter a number of Breakpoints
for head and flowrate (P730-793), which is either provided by the
manufacturer or created based on the dimensions of the device.
Select from the following options:
1 = Universal Linear flow calculation
2 = Universal Curved flow calculation
3 = Universal Linear Area x Velocity (Optional)
4 = Universal Curved Area x Velocity (Optional)
P702 Calculation
Select the required calculation method, both will give the same answer, but
the difference is the information required to complete the calculation. For
ratiometric it is normally sufficient to know the maximum flow at the
maximum head. Choose between:
1 = Absolute
2 = Ratiometric (Default)
