SonaVuTM
Multi-frequency Ultrasound and Acoustic Imaging Camera
Bring your condition monitoring program into focus.
What is an Acoustic Imaging Camera?
SonaVu™ is an acoustic imaging camera. Using its 112 ultrasound sensors and optical camera, it can detect sources of airborne ultrasound and transmit them into a visual image on its touch screen. Defects such as compressed air system leaks, compressed gas system leaks, vacuum leaks, the presence of partial discharge on electrical assets, and failed/working steam traps all create turbulence. And when there is turbulent flow present, there is airborne ultrasound. SonaVu™ makes the superhuman hearing capabilities of SDT Ultrasound Devices visible to the human eye.
Using an acoustic imaging camera these defects and failure modes can be visualized and pinpointed from up to 50 meters away. And due 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.
Compressed Air Leak Management
If it’s been a while since your last ultrasound compressed air survey, or you’ve never even performed a compressed air leak survey at your facility, then it is likely that your compressed air system is riddled with leaks. A poorly maintained compressed air system can negatively impact product quality and slow production efficiency… not to mention majorly impact plant-wide sustainability.
There are several reasons why a leaky compressed air system is low on the priority list for maintenance staff.
- It could be because some don’t associate compressed air with energy consumption.
- It could be because not all maintenance technicians are aware of the fastest and easiest way to locate compressed air leaks.
- It could be because maintenance doesn’t like to take out the ultrasound detector and simply finding leaks, tag them and fix them.
- It could be because we can’t find the time in our busy days to do the little things that require elbow grease like repairing some air leaks and accumulate thousands in energy savings.
The bottom line is – a leaky system will never fulfill production demand, continually drain resources, and harm the environment as additional and unnecessary greenhouse gas emissions accumulate and fill our atmosphere.
With SonaVu™ performing a compressed air leak survey and locating those pesky leaks has never been easier. Also, since SonaVu™ can pinpoint leaks from up to 50 meters away, even leaks hard to reach compressed airlines won’t go undetected.
Electrical Asset Reliability
Unreliable electrical machines and equipment can cost manufacturers millions of dollars in downtime and repairs. And even more threatening… they have the potential to injure and kill workers without warning. But it doesn’t have to be this way. Before an electrical asset reaches the point where a dangerous phenomenon like arc flash and arc blast can occur, there are tell-tale signs that the asset is becoming unstable. And the biggest key to avoiding these costly and dangerous electrical malfunctions is early detection.
Partial discharge is the first sign of a deteriorating electrical asset. And the effects of partial discharge produce airborne ultrasound signals, easily detectable with SonaVu™. You can find sources of partial discharge on all types of high voltage electrical assets. Switchgear, transformers, overhead lines, and underground cables to name a few.
Reducing Fugitive Emissions
Fugitive Emissions are a stain on oil and gas production facilities. In many cases, they’re just considered to be part of the industrial process, as they are categorized as equipment leaks and accidents, and equipment failures. But this intentional neglection of fugitive emissions comes at a cost… As they leak into the air we breathe, several dangers can arise. While some fugitive emissions only result in unpleasant odors… Some can pose a serious safety threat to both plant personnel and those living near the facility.
SonaVu™ is capable of detecting fugitive emission gas leaks in most environments. When a compressed gas leaks from a high-pressure such as inside a pipe or valve, to a low-pressure zone like our atmosphere, there is a differential pressure created which produces ultrasonic turbulence. Scanning hot zones for fugitive emissions with your SonaVu™ will reveal sources of dangerous and costly leaks. Moreover, inspectors need not worry about scanning for leaks inside or outside, as the ultrasonic detection capabilities of SonaVu™ is not affected by wind.
