How it works
Many physical processes, such as gas leaks, partial discharges or mechanical defects, create acoustic emissions (AE). Ultrasounds are often the first indication that an element is starting to fail, well before heat/infrared emissions (if any).

How does ultrasound imaging work
From sounds to images
The surface of the Distran ultrasound cameras comprises dozens of sensors that measure the sound field. When an ultrasound wave hits the surface, each sensor detects it at a different time. These differences are used to locate the ultrasound sources and overlay their location on a video image.
- Detect any gas type, even compressed air, vacuum, and steam leaks.
- Pinpoint gas leaks without scanning each single element.
- Take into account an unlimited number of sources simultaneously.

DeepRange:
Extended sensitivity to reveal smaller leaks in noisy environments… that others miss!
Listening for a faint leak beside a roaring machine or in the presence of a bigger leak is like trying to see stars in broad daylight. The sun generates too much light for the naked eye to see the stars. It is the same for gas leaks: the stronger signals overwhelm the weaker ones, and with conventional acoustic cameras, the quietest sources cannot be detected.
Distran is the first to solve this challenge. Our algorithm separates sound levels in real-time and within a single exposure, processes them intelligently, and recombines them into a single image with a much deeper range of signals. The result: we lift the limits of traditional acoustic imaging, revealing faint leaks even when they occur next to loud noise sources, such as larger leaks, compressors, or ventilation systems.
The improvement is substantial; the cameras equipped with DeepRange have drastically more sensitivity. For inspectors, this is more than an upgrade: it is a breakthrough that unlocks leak detection in conditions where it was previously impossible, setting a new standard for acoustic imaging.
Quantification of gas leak rate
From sounds to gas leak rate
In addition to locating the leak, Ultra Pro 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).
