Element Description
Correlation curve
Sensor numbers of the two devices whose data are correlated.
Time distance from the middle of the pipe line to the leak.
The color of the numbers shows how reliable the result of this
correlation is:
green ... "good" correlation, reliable result
yellow ... correlation is not optimal
red ... bad correlation; no leak or no clear
localization possible
negat. value ... the leak is on the left from the center of the
line
posit. value ... the leak is on the right from the center of the
line
