Why use Distran Ultra Pro X for hydrogen leak detection?

Hydrogen is enjoying an unprecedented momentum and is used in transportation, storage and many industrial processes. Supplying it to industrial users is a major business around the world.
Indeed, many countries directly support investment in hydrogen technologies. Furthermore, in Europe, the European Commission has set ambitious goals to increase the use of hydrogen over the next few years.
Hydrogen production, storage and transportation pose technical challenges, as hydrogen is highly flammable and checking for leaks is an essential step for its safe use. Ultra Pro X enables operators to perform fast and safe inspections.

Applications

  • Ultra Pro X helps in performing predictive maintenance for high-availability plants.
  • Urgent leak searches on assets
  • Inspections prior and after planned maintenance activities
  • Routine checks for toxic or explosive gases
  • Cost-effective maintenance of systems using atmospheric gases (compressed air, nitrogen, argon…)

Description

The ultrasound camera Ultra Pro uses 124 integrated microphones to locate ultrasound emitted by leaks of all types of gases and vacuum. The location of the sound source is indicated in real-time on an integrated screen. Pictures and videos can be recorded and integrated into digital reports with Distran Audalytics.

Ultra-Pro-Distran

Features

  • Pinpoint leaks of any gas in realtime
  • Inspect from a safe distance of up to 150ft (50m)
  • Take pictures and videos of detected leaks
  • Real-time leak rate estimation to set priorities
  • The system integrates a reporting system

Technology

At the core of Ultra Pro are the multiple sensing elements included in its head. When a sound wave hits the surface of the device, it reaches the elements at times that differ of less than a millisecond. These little time differences are processed by the device in real-time to display the location of the sound sources.

Hydrogen leak detection offers key advantages

  • Ultra Pro X is an ultrasonic camera that pinpoints hydrogen leaks from the sound they make. The operator is able to spot leaks from a safe distance, without needing to make contact with the gas.
  • Ultra Pro X is also able to quantify leak rate in L/h to help operators prioritize maintenance.
  • Ultra Pro X is an ATEX certified camera for zone 2 class IIC, including hydrogen.

Here is The Key Data

  • We use a phased microphone array of 124 elements to pinpoint leaks at a typical distance of 13 to 20 feet (4 to 6 meters).
  • 3.3 Lbs (1.5 kg) single handed device, ATEX certified.
  • Detect leaks as small as 1 L/h at 3 feet (6.10-4 cfm at 1 meter) and 5 L/h at 16 feet (3.10-3 cfm at 5 meters).
  • It can quantify hydrogen leaks.

How It Works?

Leaks generate ultrasounds
that cannot be heard by humans.
Ultrasounds Are 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).

We Convert Sounds Into Images


Dozens of sensors on the surface of Ultra Pro listen to the sound field and detect ultrasound waves at different times. This information is used to locate the ultrasound sources and represent them as a picture. Ultra Pro can handle an unlimited number of simultaneous sources.
 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 Pro takes into account an unlimited number of simultaneous sources.

We Achieve Blazing Fast Ultrasonic Imaging


In a dozen of milliseconds, Ultra Pro 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.

We Can Determine The Gas Leak Rate From The Sounds


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).

FAQ

Most frequent questions and answers

Depending on the flow rate of the leak, from 1 feet(30 centimeters) to 150-300 feet(50-100 meters). Large leaks (thousand of liters per hour) can be detected up to 150 feet(50 meters). Small leaks (a few liters per hour) are detectable at a few meters. Typical leak search distance is between 3 to 20 feet(1 to 6 meters).

Ultra Pro does not detect gases directly but the sound leaks make when the gas is escaping. Thus, leaks of any gas type can be detected by the camera, and a 50 mbar (0.7 psi) difference in pressure is recommended for good detection, along with an open path in the air for the sound to propagate. Hydrocarbons, hydrogen, noble gases, compressed air, steam, etc., can be detected by Ultra Pro, which is not limited to gas types. Negative pressures are also detectable, so Ultra  Pro can pinpoint vacuum leaks too.
Below 50 mbar, 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).

 

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.

 
Direct sight is not required for leak detection, but for the sound to propagate from the leak to the surface of Ultra Pro, where the microphones are located. This condition is typically not met for underground systems, which are shielded by soil. For insulated systems it depends on how tight the insulation is.
 

Similar to an optical camera, the accuracy is determined in terms of an angle, where the linear accuracy decreases as the proximity to a leak increases. The accuracy is dependent on factors such as the acoustic imaging algorithm, imaging frequency, and the quality of the match between the optical camera and the microphone array.
The typical accuracy is about 1°.

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.
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.
