CPL has a new high-performance Water Leak Correlator that is able to locate leaks in pipes of any type or size, without having to disrupt the system and shut it down. By placing sensors on two points of the pipe, the correlator is able to calculate how far the leak is from each point. Water leak noise correlation listens for water leak noises and calculates the distance to the leak. A leak in a pipe under pressure creates noise that travels through the pipe walls. The noise is detected at two separate points, (water valves, hydrants, meters) by highly sensitive microphones. Using the pipe diameter, pipe material and pipe length, the exact leak position can be calculated accurately and quickly.

There are many benefits to using a leak correlator. It is very useful in finding leaks on larger pipes: mains in the streets, fire mains, large lines in MHP, and large commercial facilities.
