Page 6: Introduction
1 Introduction System Overview Eureka3 is a high performance leak noise correlator used for the location of leaks in buried water pipes. The system combines sophisticated technology with flexible operation to locate leaks in difficult conditions, e.g. where there is substantial background noise, where only the quietest of leak noise is present, or with a variety of pipe materials. -
Page 7: Principles Of Leak Noise Correlation
Eureka3 User Manual 2 Principles of Leak Noise Correlation Leak noise correlation is used to detect leaks in pipelines where there is a positive internal pressure, such that a leak causes a loss of fluid to the outside. The movement of fluid through the leak causes rapid pressure changes around the site of the leak such that there is a randomly varying noise source located at the leak. -
Page 8: Leak Beyond Sensors
Eureka3 User Manual 2.2.1 Leak Beyond Sensors If the leak is located outside the length of pipe between the sensors, then the correlator will ignore the transit time from the leak to the nearest sensor, as this transit time will be the same for both sensors. -
Page 9: System Components
3 System Components Transmitters Eureka3 has two transmitters, one red and one blue. They both listen to noise which is transmitted to PrimeTouch via an internal radio transmitter. The transmission frequency of each transmitter is different to distinguish the different noise signals. -

PrimeTouch. A metal plate can be attached to the bottom of the transmitter to provide stability to the unit. External accelerometers from previous Eureka correlation units are compatible with Eureka3 transmitters. -

The over temperature state may occur when charging in high temperatures. The transmitter electronics will manage this state and continue to charge when possible. The fault state indicates a problem and the transmitter should be returned to a Primayer Service Centre for further investigation. -

PrimeTouch. Connect the mains adaptor to the main electrical supply or the vehicle charge lead to the vehicle supply (12Vdc). Only Eureka3 charge leads should be used to charge the PrimeTouch. DO NOT attempt to use Eureka2 or Eureka Digital charge leads, as damage may occur which will not be covered by warranty. -
Page 15: Charge Time
Eureka3 User Manual 3.2.9.1 Charge Time Charge time from flat to full is between 3 hours 45 minutes and 4 hours 30 minutes. The charge time will be longer in higher temperatures; there is automatic monitoring in the electronics to prevent the batteries overheating. -
Page 16: Deployment

Page 17: Setup Transmitters
Eureka3 User Manual 1. Open the hydrant carefully to ensure there is no debris in the outlet, and clean water flows (the pressure can be assessed at this point). 2. Ensure the hydrant valve is shut. 3. Ensure the seal in the hydrophone is clean. -
Page 18: Velocity
Eureka3 User Manual 4.8 Velocity An accurate sound velocity is necessary to obtain accurate leak location from the correlation result. In most cases the sound velocity that is automatically used when entering the pipe diameter and material will be adequate. However, it is always highly recommended to check and correct the sound velocity in the pipe to reduce leak position error. -

A lightning symbol is shown in the battery icon when PrimeTouch is charging. If this symbol is flashing when the charger is attached there is a charging issue. This could be due to high temperature. Unplug the charger for at least an hour. If this problem persists then please contact Primayer Customer Support. -

Questions and answers
Prime Touch not charging. Not turning on when not plugged in the charger. when plugged in the charger it is turning on but only for the last 5-10 seconds.
The Primayer Eureka3 PrimeTouch may not be charging properly due to the use of an incorrect charge lead. Only Eureka3 charge leads should be used, as using Eureka2 or Eureka Digital charge leads can cause damage that is not covered by warranty. Additionally, if the device is exposed to high temperatures, it may enter an over-temperature state, delaying charging. If the issue persists, it may indicate a fault, and the unit should be returned to a Primayer Service Centre for further investigation.
