LEAK LOCATION, DETECTION & CORRELATION

Correlation
leak location correlation

The technique of correlation is used to find and pin-point the leak in a water distribution network.

Leak Location

If two acoustic sensors are attached at different locations on a pipe with a leak. The leak sound will take longer to reach the sensor furthest away from the leak. This is known as the Time Delay or ∆t. Utilising the time delay and other information such as pipe diameter, pipe material and length between the two sensors the exact leak position can be indicated by the Eureka or Enigma correlator.

eureka-3-leak-location
EUREKA 3
Portable correlator for leak detection. Proven world-wide it can be used on metallic, plastic and cement pipes. Every leak detection team should have the Eureka kit.
eureka digital-leak-location
EUREKA DIGITAL
Delivers optimum performance in difficult leak detection situations, such as substantial background noise or a quite leak noise.
enigma-leak-location
ENIGMA
Multi-point correlation system that combines noise logging and correlation into one operation.
enigma-hyq-leak-location
ENIGMA hyQ
A high sensitivity hydrophone is added to the Enigma logging correlator and together with added filtering software enables successful leak location in buried, large bulk or trunk mains.
