Online correlation

If you evaluate the correlation as “good”, in the next step provide information on the
properties of the pipe section in order to be able to calculate the distance to the leak.
Proceed as follows:
Step Description
1
Click on the
Insert pipe data
button, located between the two diagrams.
Result:
The menu for entering pipe data opens.
2
Enter information on the measurement path regarding its length and properties.
•
Using the
Add
and
Delete
buttons you can divide the represented section in
subsections.
•
For each section or subsection, enter the
length
of the pipe.
•
For each section or subsection, select the
material
of the pipe from the
drop-down list. (Individual entry is not possible.)
•
For each section or subsection, select the
diameter
of the pipe from the
drop-down list. (Individual entry is not possible.)
The value for the
sound velocity
is calculated by the software using the pipe
material and diameter and it is entered automatically.
If the actual sound velocity in the pipe is known, for example from a previous
sound velocity measurement, you can enter the value into the field yourself.

Confirm with
OK
.
Result:
In the correlation menu, the distance from transmitter
A
or
B
to the leak is
now shown.
