The velocity value is then displayed and shown as calculated. The
manufactured leak is then turned off, allowing for location of the unknown
leak with improved accuracy.

Note:

Measuring velocity using this method does not account for

more than one pipe material because it can only measure the
average velocity over the given pipe length.

Velocity Calculation (3-Transducer Mode)

This mode involves three transducers and the actual leak (i.e., no
