Distran Ultra Pro

Redefining Standards in Gas Leak Inspection

The Ultra Pro hand-held ultrasound imaging camera is capable of accurately locating gas leaks from several meters with unrivaled speed. It excels in finding leaks in high or in hard-to-reach areas.

The sensor works by detecting the specific sounds that pressurized gas leaks emit. Thanks to its integrated 124 ultrasound microphones, the ultrasound camera reconstructs the position of the sound source. The information is overlaid in real-time with a wide angle optical image.

Ultra Pro creates, in a single tap, images and videos that can be assembled in reports either using Distran’s reporting software Audalytics or with the user’s preferred software.

Pinpoint Gas Leaks Without Scanning Each Single Element

Ultrasonic Gas Leak Imaging is a technique that allows you to analyze the sound emitted by leaks and and display it as an image. It works for any gas type, even vacuum.

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).

From Sounds to Images

The surface of Ultra Pro is composed of 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 to a video image. Ultra Pro takes into account an unlimited number of sources simultaneously.

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).

Why Use Ultra Pro?

10 Times Faster than Traditional Methods

Classical gas detectors require the operator to thoroughly check every potential leak point. With Ultrasonic Imaging, the detection can be performed without scanning every single element. The inspection is done several meters away, reducing the need for scaffolding.

Reduce Your Exposure to Gas

Leaks can be found several meters away (for bigger leaks up to 100 meters away). The operator has less or no exposure to the hazardous location.

Uncover Leaks in Unexpected Locations

As sound propagates beyond our line of sight, hidden leaks that are missed with other techniques can be detected with Ultrasonic Imaging.

Quantify Leak Rate

Ultra Pro is able to quantify the leak rate (in liters per hours or in cubic feet per minute) in a few seconds without using a tripod.

Estimating Gas Leak Rates Has Never Been this Easy

Thanks to its 124 sensors, Ultra Pro can not only locate leaks but also quantify the severity of a gas leak within seconds and without the need for a tripod. From the sound source loudness, a gas flow rate is automatically converted in real-time. It is not affected by the background noise. The leak rate quantification makes it possible to prioritize the maintenance and inform the decisions regarding the repair of the leaks.

Additionally, the ultrasonic camera Ultra Pro estimates, in real-time, its limit of detection in the current environment given the user selected settings. It enables the operator to validate his inspection.

Ultra Pro Also Pinpoints Partial Discharges and Other Electrical Faults

Partial discharges such as Corona discharges, arcing and tracking happen in high-voltage systems and may lead to failures. These phenomena produce ultrasound and can be precisely localized with Ultra Pro.

Get Outstanding Reports

Ultrasonic imaging shines when it comes to reports because images speak more than a thousand words when it comes to describing a leak location. Furthermore, Distran has developed an integrated reporting tool, called Audalytics, that enables the operator to create a report with annotations within minutes after the inspection. The report can then be shared within all stakeholders without additional software, directly in the browser where videos are embedded seamlessly.
Special software features allow data-trending, dashboard functions and recording of voice notes.
