Introduction
Since the initial development of leak noise correlators in the mid 1970s, these
instruments have demonstrated unsurpassed performance in effectively
locating leaks in pipe networks. Leak location using a correlator provides a
degree of precision unavailable through any other method, particularly in
environments exhibiting high noise levels. As a result, correlators are now
standard tools in leakage control.
Early correlators were bulky, difficult to use, and, therefore, had to be
mounted on vehicles. Modern technology, accompanied by the ongoing
development of microprocessors, has resolved these issues. The current
equipment is now truly portable and much easier to use.
The ADS
®
Eureka2R correlator represents a new generation of these
instruments, providing new levels of miniaturization, sensitivity, accuracy,
and ease-of-use for pipe network applications. The Eureka2R provides
enhanced durability and operational speed. The 3.3-pound (1.5-kg) instrument
can be carried in one hand, and the entire kit fits in a rugged carrying case for
transportation. The integrated, rapid-charging battery (typically charging 75%
in 1 hour) minimizes service time.
The Eureka2R uses DSP (Digital Signal Processor) technology, a RISC
(Reduced Instruction Set Computer) processor, and notch filters to optimize
ultra-low frequency processing. Since these frequencies travel furthest in
pressurized pipes, Eureka2R has a specialized correlation mode for optimum
performance on large diameter and plastic pipes.
This instrument can print paper reports on-site or store data for future display,
analysis, or output. Under normal operating conditions, the Eureka2R can
store several weeks of data.
