Introduction
The ADS
®
Eureka Digital System is the latest model in the proven Eureka
family of high-performance leak noise correlators designed for locating
leaks in buried water pipes. Combining advanced technology, operational
flexibility, and simplicity, Eureka Digital offers a comprehensive solution
for leak location, even under conditions ranging from substantial
background noise to minimal leak noise. This system is effective on
metallic, plastic, and cement pipes.
The Eureka Digital provides the following benefits:
 Optimum performance under difficult leak detection conditions
 Operation not limited by radio range
 Digitally recorded sound for repetitive analysis
 Optional direct transmitter connection to pipe (street-work
friendly)
 Three-sensor input for automatic velocity measurement
 Flexible operation
Eureka Digital uses the same technology as the successful Enigma
®
multi-
point correlation system, a system that has demonstrated outstanding
performance in leak location.
The system offers two methods for determining the leak position: 2-
transducer and 3-transducer. The 2-transducer method involves
positioning the red and blue sensors at either side of the suspected leak
position. The system then measures the amount of time required for the
leak sound to reach the respective sensors. The Eureka Digital then
determines the leak position based on the known velocity of sound and
distance between the sensors.
