Here's an overview of three acoustic leak detection solutions provided by Echologics.
EchoShore-M is an acoustic leak detection solution that uses advanced signal processing and acoustic sensor design to locate “quiet leaks” and filter out background noise commonly experienced on large diameter pipeline assets.
It can accurately locate leaks on virtually any type of pipe material including plastic mains. After bracketing a section of the transmission main with two magnetic surface mounted sensors, or hydrophones and recording an acoustic noise file, the leak noise data is captured and uploaded to a computer for analysis.
Echologics' ePulse condition assessment approach identifies the condition of both distribution and transmission mains, while simultaneously searching for leaks, all without the need for large excavations or service disruptions.
The technology measures the actual strength of the pipe wall by placing a microscopic flex on the pipe walls using sound waves. Acoustic sensors are attached to existing contact points, such as fire hydrants, valves or directly in contact with a pipe, where it captures the time it takes the sound wave to travel between two sensor stations to dictate the condition of the pipe wall.
The EchoShore-DX platform is a fixed leak detection technology that incorporates the latest generation of acoustic sensors. The sensors, which are embedded in an intelligent node, are built into a standard fire hydrant cap and are capable of identifying extremely faint acoustical noises emitted by leaks before they become detectable by conventional methods. This early detection capability enables utilities to prioritize repair based on actual need and the most effective allocation of repair crews.
