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.

Ultrasonic Gas Leak Detection
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.
Benefits
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.
Quantify gas leak rates and prioritize maintenance
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.
Locate partial discharges, such as corona, tracking, arcing
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.
Inspection reports with Audalytics
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.
Best ultrasonic camera
Best-in-class handling in the field
From the beginning, Ultra Pro has been developed with industrials and by people who have performed many inspections in the past. Weighing only 1.5 kg including the battery, the camera is operated with a single hand, so that the operator can safely inspect, even in a staircase. The camera has also been tested for drops, in design to be robust. Its integrated LED lighting illuminate dark areas without the need for a separate light source.

Robust design
The only ATEX Certified ultrasound camera in the world
In January 2021, Distran announced the Ultra Pro X, the world’s first ATEX certified ultrasound camera.
Ultra Pro X is the ATEX certified version of Ultra Pro, specifically designed for use within potentially explosive atmospheres for the oil and gas, chemistry and power plant industry.

Frequently Asked Questions
What distance can a leak be detected?
Depending on the flow rate of the leak, from 30 centimeters (1 feet) to 50-100 meters (150-300 feet). Large leaks (thousand of liters per hour) can be detected up to 50 meters. Small leaks (a few liters per hour) are detectable at a few meters. Typical leak search distance is between 1 to 6 meters (3 to 20 feet).
What type of gases can be detected?
A difference in pressure of 50 mbar (0.7 psi) is recommended for good detection. Below this, it is still be possible to detect gas leaks, but the detection limit of the device is higher. The difference can also be negative (vacuum leaks).
Which gases can be detected ? Does it work with vacuum leaks?
The camera does not detect gases directly but the sound leaks make when the gas is escaping (learn more about technology). Vacuum leaks can also be detected because they create turbulences and thus ultrasounds. What is needed is a minimum pressure difference (typically 50 mbar / 0.7 psi) and a path in the air for the sound to propagate.
Is it possible to operate Ultra Pro in noisy areas (compressor rooms, gas turbine enclosure, etc.)?
Ultra Pro filters all noises outside the detection window, in particular low frequency in the audible range. Even in a very noisy environment like in gas turbine noise enclosure with up to 100 dB(A) noise, leakages have been detected.
Ultra Pro estimates in real-time its lower limit of detection (LoD), allowing the user to know how accurate the inspection is. This is typically useful when acceptance criterion is used.
Can I inspect underground or insulated systems?
Direct sight is not required for leak detection, but the sound must propagate from the leak to the surface of Ultra Pro, where the microphones are located. This is typically not the case for underground systems (shielded by soil). For insulated systems it depends on how tight the insulation is.
What is the accuracy of Ultra Pro?
Similar to an optical camera, the accuracy is determined as an angle (the closer you are to a leak, the smaller is the linear accuracy). The accuracy depends on the acoustic imaging algorithm, the imaging frequency and how good the optical camera and the microphone array are matched.
The typical accuracy is about 1°.
Is the device ATEX Certified / Intrinsically Safe?
Ultra Pro X is the ATEX certified / intrinsically safe version of Ultra Pro. It is certified for zone 2 gas for class IIC (USA: div 2 class 1), including hydrogen.
Does Distran supply a tool to generate digital reports?
Yes. With every device, Distran includes free access to its reporting tool Audalytics. Pictures and videos can be included in reports along with notes and comments. It is easily shared between stakeholders.
