Offline correlation (Multipoint measurement)
74
The Multi correlation gives you an overview of the noise situation along the measured
pipeline. In the ideal case, the pipe sections where leaks are most likely can be
identified at a glance.
Rate the displayed correlations.
If the Multi correlation shows at least one "good correlation" with one clear peak, the
probability of a leak between the respective sensors is high.
Take a closer look at the good correlations. Tap the relevant thumbnail. The
Correlation menu for this sensor pair appears.
Rate correlations
"Bad correlation"
• more than one peak
• lag value is yellow or
red
• lag value is zero or
nearly zero
No leak or no clear
localization possible
"Good correlation"
• clear peak
• lag value is green
• lag value is not zero
Probability of a leak
is high
