4.3 Mean Axial Velocity Method (1/8 Diameter)

1.

Determine the internal diameter D of the pipe, in millimetres, by the most accurate method available.

2.

A profile factor F

p

 of 1 must be used.

3.

Calculate the insertion factor

F

i

 = 

Example

 – for a pipe of internal diameter 593mm (23.35in):

F

p

 = 1

F

i

 = 

F

i

 = 1.074

4.4 Partial Velocity Traverse

Refer to the Appendix A1 for procedure.

4.5 AquaProbe Transmitter Setup

The AquaProbe Transmitter can be set up to display point velocity, mean velocity or flow rate, as required.
For full programming details refer to the AquaProbe Quick Reference Guide.
