Appendix A

A.1 Testing the Flow Profile for Symmetry

If there is any doubt as to the symmetry of the flow profile (see section 2.2, page 6), a Partial Velocity
Traverse should be carried out. This procedure involves comparing the value of velocity at two points at
equal distances from the centre line.

It is normal to compare the flow velocities at insertion depths of 1/8 and 7/8 of the pipe diameter as these
points are always on the 'knee' of the profile.

A.1.1 Partial Velocity Traverse

Determine the internal diameter D of the pipe, in millimetres, by the most accurate method available. If the
AquaProbe insertion length is greater than the internal diameter of the pipe, proceed with the Single Entry
Point Method detailed in Section A.1.2. If the AquaProbe insertion length is less than the internal diameter
of the pipe, proceed with the Dual Entry Point Method detailed in Section A.1.3.

A.1.2 Single Entry Point Method

1.

Insert the probe to a depth of 1/8 the pipe diameter – see Fig. 2.14.

2.

Calculate the insertion factor

F

i

 = 

3.

Refer to the AquaProbe Transmitter Configuration Manual and enter a Blockage Factor (BL) of value
equal to F

i

.

4.

Record the flow velocity reading.

5.

Insert the probe to a depth of 7/8 the pipe diameter.

6.

Calculate the insertion factor

F

i

 = 

7.

Refer to the AquaProbe Transmitter Configuration Manual and enter a Blockage Factor (BL) of value
equal to F

i

.

8.

Record the flow velocity reading.

9.

Calculate the ratio of the two values recorded.

If the ratio is between 0.95 and 1.05 the flow profile is acceptable and the procedure detailed in section 4.2
can be used. If outside this ratio the AquaProbe should be resited for optimum accuracy.

Note.

Due to software configuration, all calculations are in metric units. Therefore if using an imperial 

pipe, the diameter 

MUST

 be converted into millimetres (1in = 25.4mm) i.e. a 36in pipe = 914mm.
