Acoustic Leak Detection – WA-EUS-750 Acoustic Leak Imager

The WA-EUS-750 is a compact ultrasonic acoustic imaging tool designed to visually locate compressed air and gas leaks quickly and accurately.

By converting high-frequency leak noise into a real-time visual sound map, maintenance teams can identify leak sources from a distance — even in complex and noisy plant environments.

With fast scanning and clear visual indication, the WA-EUS-750 helps teams prioritize repairs, reduce troubleshooting time, and cut energy losses caused by compressed air leaks.

Gas leaks generate ultrasonic sound (typically above 20 kHz) due to turbulence when gas escapes from a higher-pressure region through a small opening.

This sound is highly directional, which makes it ideal for pinpointing leak locations.

The WA-EUS-750 converts ultrasonic information into an easy-to-interpret visual display, allowing faster leak finding with less operator guesswork.

How Does the WA-EUS-750 Acoustic Leak Imager Find Leaks?

The WA-EUS-750 picks up the high-frequency sound that escapes with a leak and shows it as a real-time sound map on the display. Instead of listening for a tone and moving in until you find the source, your team can see where the sound is coming from, which cuts down on guesswork.

This also means leaks can be spotted from a distance, so hard-to-reach pipes and overhead lines can be checked without climbing or shutting anything down. If you prefer a simple handheld tool that gives an audible tone, the WA-EUS-740 leak detector is the lightweight alternative for routine rounds.

Where Can an Acoustic Leak Imager Be Used?

An acoustic imager suits plants with long pipe runs, many joints and a lot of background noise, where walking the line with a handheld tool takes a long time. Fast scanning lets a maintenance team check several areas in one round and pick out more than one leak at a time.

Foundries and steel plants are a good example, with their heavy machinery, noise and widespread piping, as described in our guide to compressed air monitoring for steel plants and foundries. The same approach works for any noisy production area where leaks are hard to hear.

How Does the WA-EUS-750 Help Prioritize Leak Repairs?

Not every leak is worth fixing first. The visual display makes it easier to see which leaks are stronger, so repairs can start with the sources that waste the most air. This is useful during audits and routine maintenance rounds, when time is limited and the repair list can be long.

Once the leaks are tagged, the compressed air leak cost calculator gives you an estimate of what they cost each year. That helps your team explain the value of fixing them and decide where to start.

Automotive plants use compressed air across pneumatic tools, assembly equipment, automation systems, and production machinery. The WA-EUS-750 helps maintenance teams visually locate leaks from a distance, including overhead pipework and hard-to-reach areas, enabling faster repairs and reduced energy loss.

Textile plants rely on compressed air for various pneumatic machinery and production equipment. The WA-EUS-750 makes it easier to scan large areas and identify leak sources quickly, helping maintenance teams prioritize repairs and improve compressed air system efficiency.
