If P700 = 3 (BS 3680 Weir)<br />
Select from the following options:<br />
1 = Rectangular<br />
2 = V-Notch Full 90 degree (full 90 o )<br />
3 = V-Notch 53 degree 8’ (half 90 o )<br />
4 = V-Notch 28 degree 4’ (quarter 90 o )<br />
5 = Broadcrested (Rectangular) Weir<br />
If P700 = 4 (Area Velocity)<br />
The calculation of flow using Velocity Area is only possible when the<br />
“speedy” velocity sensor is used to provide an input signal proportional to<br />
the velocity of the flow.<br />
Select from the following options:<br />
1 = Circular Straight (U-Channel), circular bottom, straight sides.<br />
2 = Rectangular<br />
3 = Trapezoidal<br />
4 = Round Pipe<br />
If P700 = 5 (Special)<br />
Select from the following options:<br />
1 = Palmer-Bowlus Flume<br />
2 = H-Flume<br />
3 = V-Notch angle (other than BS3680)<br />
If P700 = 6 (Universal)<br />
Where the Primary Measuring device does not match any of the devices<br />
contained in the above categories then a universal volume calculation can be<br />
performed. A head Vs flow chart is used, to enter a number of Breakpoints<br />
for head and flowrate (P730-793), which is either provided by the<br />
manufacturer or created based on the dimensions of the device.<br />
Select from the following options:<br />
1 = Universal Linear flow calculation<br />
2 = Universal Curved flow calculation<br />
3 = Universal Linear Area x Velocity (Optional)<br />
4 = Universal Curved Area x Velocity (Optional)<br />
