System Features
The following sections describe some of the components and features
included in the ADS Eureka Digital System.
Transmitters
The transmitters offer real-time (radio) operation or delayed recording
(logging) operation, which eliminates radio range problems associated
with conventional correlators. A transmitter also includes an integrated
sensor that can connect directly to the pipe. This allows the chamber cover
to be closed, resulting in much less of a disruption to traffic.
Automatic Velocity Measurement
Every Eureka Digital can operate with three sensors without requiring a
third transmitter. The third sensor connects directly to the receiver
module. Three sensors provide the capability for measuring velocity,
improving leak location accuracy and significantly reducing the
opportunity for dry holes.
In-Case Battery Charging
The transmitter and receiver module batteries can be charged in the
transportation case from either a vehicle 12Vdc or mains supply. This
offers additional flexibility because battery charging can occur while
traveling between sites.
Advanced Analysis Software
Eureka Digital provides software tools for the following:
 Spectral analysis of leak sound
 Advanced correlation, coherence, and filtering
 Optional manual filter control
 Audible and visual inspection of leak noise
 Pipe material and velocity modification following results
computation
 Optional user-defined pipe materials and velocity tables
 Tracker function for selecting the best portion of recorded sound to
retrieve the correlation peak
