SonaVu™ Converts Sources of Airborne Ultrasound into Visual Images

SDT’s SonaVu™ is an acoustic imaging camera, which can identify sources of airborne ultrasound and translate them into a visual image on its touch screen. This is achieved with the help of its 112 ultrasonic sensors and an optical camera.

Turbulence is produced by defects like compressed gas system leaks, pressurized air system leaks, vacuum leaks, partial discharge on electrical assets and failed/working steam traps. When there is turbulent flow, there is also airborne ultrasound. SonaVu™ makes the superhuman hearing abilities of SDT Ultrasound Devices visible to the naked eye.

Using an acoustic imaging camera, defects and failure modes can be pinpointed and visualized from up to 50 m away. Thanks to the visualization capabilities of SonaVu™, it’s really easy to use too. With minimal device training, maintenance technicians can confidently inspect their assets for defects, long before they cause unexpected downtime.

By bringing sound into focus, SonaVu™ can help you find compressed air leaks.

System leaks take away 35–40% of demand, with electricity accounting for 75% of costs. As a result of leaks, profits are lost and the environment is polluted.

Compressed Air Leak Management

If it has been a while since the last ultrasound compressed air survey, or if the user has never performed a compressed air leak survey at the facility, the compressed air system is likely to be riddled with leaks. A poorly retained compressed air system can have a negative impact on product quality and production efficiency, as well as have a significant impact on plant-wide sustainability.

There are several reasons why a leaking compressed air system is low on the maintenance staff's priority list.

  • Some people do not associate compressed air with energy consumption
  • Maintenance personnel dislikes using the ultrasound detector to locate leaks, label them and repair them
  • Not all maintenance technicians are aware of the quickest and easiest way to locate compressed air leaks
  • Users do not have time in their busy schedule to do the little things that require elbow grease, such as repairing some air leaks and saving thousands of dollars on energy

A leaking system will never meet production demand, will constantly drain resources and will harm the environment by accumulating and filling the atmosphere with additional and unnecessary greenhouse gas emissions.

Performing a compressed air leak survey and locating those pesky leaks has never been easier with SonaVu™. Furthermore, because SonaVu™ can detect leaks from up to 50 m away, even hard-to-reach compressed airlines will not go undetected.

Electrical Asset Reliability

SonaVu™ can also assist in improving the dependability of your electrical assets. Unreliable electric assets cost millions in downtime and repairs, and they have the potential to injure and kill.

However, it doesn’t have to be this way. Before an electrical asset becomes dangerous such that arc flash and arc blast can occur, there are a few signs that inform users that the asset is becoming unstable. The most important way to avoid these costly and dangerous electrical malfunctions is to detect the malfunctions early on.

The first sign of a deteriorating electrical asset is partial discharge. The effects of partial discharge produce airborne ultrasound signals that are easily detectable with SonaVu™. Sources of partial discharge can be found on all kinds of high voltage electrical assets, such as Switchgear, transformers, underground cables and overhead lines, etc.

By scanning these high voltage electrical assets with your SonaVu™ users will be able to locate and document the presence of any partial discharge. Regular ultrasound inspections on electrical equipment will also reveal partial discharge at its earliest stages and keep factory workers safe.

Users can also use SonaVu™ to detect signs of insulation breakdown, which is a common cause of power outages.

Reducing Fugitive Emissions

SonaVu™ is also a secure method of detecting fugitive emissions.

The cost of fugitive gas and vapor emissions from pressured systems is high, and they contribute to global pollution. Users can identify their source from a safe distance with SonaVu™.

Fugitive gas and vapor emissions from pressured systems are expensive and contribute to global pollution. With SonaVu™, users can identify the source of fugitive emissions from a safe distance.

Fugitive emissions are a dark stain on oil and gas production plants. In most cases, they are simply regarded as a part of the industrial process and are classified as equipment leaks and accidents, as well as equipment failures.

However, this deliberate disregard for fugitive emissions comes with a price. Several dangers can arise as they leak into the air we breathe. While some fugitive emissions produce only unpleasant odors, others can pose a serious safety risk to both plant personnel and those living nearby.

SonaVu™ can detect fugitive emission gas leaks in a wide range of environments. When a compressed gas leaks from a high-pressure zone, such as inside a pipe or valve, to a low-pressure zone, such as the atmosphere, a pressure differential is created, resulting in ultrasonic turbulence.

Scanning hot zones for fugitive emissions with your SonaVu™ will reveal the location of dangerous and expensive leaks. Furthermore, inspectors do not need to worry about scanning for leaks inside or outside because SonaVu™ ultrasonic detection capabilities are not affected by wind.
