How It Works

Leaks generate ultrasounds
that cannot be heard by humans.

Ultrasounds: sounds that matter

Many processes create ultrasounds, such as gas leaks, partial discharges or mechanical defects. Ultrasounds are often the first indication that an element is starting to fail, well before heat/infrared emissions (if any).
From sounds to images

The surface of Ultra Pro Max is composed of dozens of sensors that are listening to the sound field. When an ultrasound wave hits the surface, the different sensors detect it at different times. These differences are used to locate the ultrasound sources and represent them as a picture. Ultra takes into account an unlimited number of simultaneous sources.
Blazing fast ultrasonic imaging

In a dozen of milliseconds, Ultra Pro Max is able to output an acoustic picture. This allows to locate ultrasounds in real-time and to catch the fastest events. Frequency filtering allows to discard sound sources that do not match the characteristics of a leak, resulting in selective detection.
From sounds to gas leak rate

In addition to locating the leak, Ultra Pro Max is able to estimate the flow escaping through a leak in liters per hour, based on the acoustic emission strength and the pressure difference at the leak. This allows the user to quickly asses the severity and the cost associated with the leak. Furthermore, the smallest detectable leak in the current environment is automatically displayed in real-time (patent pending).

DeepRange: Precision Leak Localization Technology

DeepRange is Distran's proprietary acoustic imaging technology that enables operators to pinpoint even the smallest gas or vacuum leaks by isolating leak-specific ultrasound frequencies from background industrial noise. It detects leaks as small as 0.15 L/h in optimal conditions (or 2 L/h in demanding industrial environments) and overlays the detected sound source onto a live video image, allowing leaks to be located safely from a distance without direct contact or point-by-point scanning.

Real-Time Leak Rate Estimation

Prioritize maintenance actions and emissions reduction efforts with greater confidence.

DCL: Detection Confidence Level

DCL is a confidence metric that helps distinguish actual gas or vacuum leaks from background noise. Displayed directly on the device's screen, the DCL threshold can be adjusted to meet specific regulatory reporting requirements or site-specific maintenance standards.

Ultra Pro Lite / Ultra Pro X Lite

If your application doesn't involve high background noise, Ultra Pro Lite delivers the same core acoustic detection capabilities at a lower cost.

Audalytics: Reporting & Data Management

Audalytics software simplifies inspection workflows by automatically generating reports with photos, videos, and annotations. It converts voice notes into text, visualizes geotagged leaks on an interactive map, and provides searchable dashboards and galleries to track findings, compare inspection results over time, and monitor leak status.
