4.8 Velocity
An accurate sound velocity is necessary to obtain accurate leak location from the correlation result. In
most cases the sound velocity that is automatically used when entering the pipe diameter and material
will be adequate. However, it is always highly recommended to check and correct the sound velocity in
the pipe to reduce leak position error. The method of velocity correction is described in section 5.6.
4.9 Filter Settings
The default filter settings will give good results most of the time. Sometimes with difficult leaks
adjusting the filters will obtain a more definitive result. Adjustment of the filters and the use of the
coherence display are explained in section 5.10.
