ADS Eureka2R Leak Noise Correlator User Manual
Trunk Mains and Plastic Pipes
It can be extremely difficult to obtain a satisfactory correlation when
examining trunk mains or long lengths of plastic pipe. The nature of these
pipe networks causes predominately low frequency leak noise because high
frequencies attenuate rapidly.
The Vector Correlate function of the Eureka2R (described in Vector
Correlate on page 27) is a technological development that significantly
improves correlation under these conditions. Vector correlation can deliver
results even when all other correlation methods fail.
