If P*700 = 3 (BS 3680 Weir)
Select from the following options:
1 = Rectangular
2 = V-Notch 90-degree (full 90
o )
3 = V- Notch 53 degree 8’ (half 90
o
)
4 = V- Notch 28 degree 4’ (quarter 90 o )
5 = Broad crested (Rectangular) Weir
If P*700 = 5 (Special)
Select from the following options:
1 = Palmer-Bowlus Flume
2 = H-Flume
3 = V-Notch angle (other than BS3680)
If P*700 = 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 several
Breakpoints for
head and flowrate (P*730-793) , 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
P*702 Calculation
Select the required calculation method , both will give similar answers, the
difference being 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)
P*703 Minimum Head
This parameter is used to enter the distance , above empty, that represents
zero head and flow . This feature is used in Primary Measuring Devices
where the zero reference is at a higher level than the channel bottom, at the
point of measure. Enter distance in
Measurement Units P*104 .
