SDT Sonavu ultrasound imaging camera for ultrasonic air leak detection and electrical asset reliability. Store, organize, analyze and report your measurements with Sonavu Insights reporting software.

SDT Sonavu Ultrasound Camera


The SDT Sonavu ultrasound imaging camera makes finding air and vacuum leaks as well as electrical faults such as corona, partial discharge and tracking easy. You will be able to see, hear and record the leaks and electrical faults. With the included Sonavu Insights reporting software you can generate leak and electrical reports and put a dollar value to found leaks.


Compressed air and vacuum leak detection

With the SDT SonaVu acoustic imaging camera performing a compressed air leak survey has never been easier. The SonaVu™ can identify leaks from up to 150 feet away, even leaks in hard to reach areas.

If you haven’t done a compressed air survey recently, or you’ve never performed a leak survey at your facility, then it is likely that your system is riddled with leaks. A leaky compressed air system can negatively impact product quality and slow production.

While compressed air systems will vary in size and cost, what remains constant is 75% of the cost of an air compressor system goes to the energy used to compress the air. With 75% of costs consumed by electricity, system leaks can eat away 35-40% of demand. Leaks erode profits.

Electrical reliability

Unreliable electrical machines and equipment can cost millions of dollars in downtime and repairs. And even more threatening, they have the potential to injure and kill workers. Figures produced by the IEEE point to insulation failure in as much as 90% of electric switchgear defects.

Age has very little influence over reliability. In fact, 80% of failures are associated with poor workmanship or quality issues. IEEE concluded that the most likely cause of electrical asset failures includes water ingress, cracked insulators, and incompetent workmanship during installation or maintenance.

The procedure for scanning is straightforward. Connect the noise attenuating headphones to the SonaVu™ and position the sensors towards potential sources. The ultrasound produced by partial discharge excites the sensors while their location is revealed on the display. Tap the icon to capture either a video or still image to place it into your inspection report. It’s that easy!

Regular ultrasound inspections on your electrical equipment will reveal partial discharge at its earliest stages and keep workers safe.

Fugitive Emissions

One problem facing refineries and oil and gas (O&G) plants is how to identify and eliminate sources of leakage into the atmosphere. Fugitive emissions is an all-encompassing term used to describe both intentional and accidental leaks.

This term brings our attention to finding and eradicating them. The threats imposed by fugitive emissions vary from unpleasant odors to serious, hazardous safety risks for plant personnel and populations living within the danger range of facilities.

The SonaVu™ from SDT Ultrasound Solutions, is a new technology for the detection of fugitive emissions within the oil and gas and refining verticals. SonaVu™ is a multi-frequency acoustic imaging camera that blends visual and auditory senses to bring fugitive emissions into focus.

When a compressed gas at high-pressure leaks from 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. Also, since the SonaVu’s ultrasonic detection capabilities are not affected by wind, inspectors can scan for leaks inside or outside. 

What is a sonavu acoustic imaging camera?

The SDT SonaVu™ uses 112 ultrasound sensors and an optical camera. It detects the sources of airborne ultrasound and converts them into a visual image on its vibrant, color touch screen.

Ultrasound is created when assets produce either Friction, Impacting, or Turbulence (FIT). There are healthy levels of FIT, but these can quickly become unhealthy as defects worsen. Compressed air leaks, vacuum leaks, gas leaks, partial discharge, fugitive emissions, squeaking, rattling, and rubbing, are just a few sources of airborne ultrasound detectable with SonaVu™ PRO.

SonaVu™ enhances routine inspections by creating a visual link to sources of FIT. It acoustically locates defects them from a safe distance while capturing their location visually in image or video format.

Using an acoustic imaging camera these defects and failure modes can be visualized and pinpointed from up to 50 meters away. And with the visualization capabilities of SonaVu, it’s easy to use too. With minimal training, maintenance techs can quickly and confidently inspect their assets for defects.
