FLIR Si124 Application Story: Can You Visualize Air Leaks? @flir #Camera #Imaging

In this application story about FLIR Si124 industrial acoustic imaging cameras, we interviewed Soichi Yagyu, president of Minaruko Co., Ltd. Yamaguchi Manufacturing General Manager. Mr. Iwade, Operation General Manager.

FLIR: Why were you worried about air leaks?

Yagyu: Every time I visited the factory on a regular basis, I was worried about the noise of the shoes at the manufacturing site. I couldn’t pinpoint where the air leak was, but I heard a swoosh. Our factory (Iga City, Mie Prefecture) uses many air compressors to manufacture aluminum powder. Usually, about 20-30% of the electricity bill is related to air in the manufacturing plant. But in our case, the rate is about 50 percent. Air leaks directly lead to additional costs, so we considered countermeasures. However, the leak is not visible and is difficult to find. If an air leak occurs in a quiet environment, listening to it will help you identify where the leak is. However, in the factory, loud and small noise prevented it. I’ve heard that FLIR Si124 helps identify leak points even in noisy environments. I knew it wouldn’t be an easy task to completely eliminate leaks because the network of air plumbing in the Mie factory was open, but I wanted to address this issue.

Many air pipes are installed not only in major manufacturing facilities but also in auxiliary facilities.

FLIR: What was your impression after using FLIR Si124?

Yagyu: The first thing I felt was that it was very easy to use and operate. You can see only the suspected air leaks with the camera without any special training or knowledge.

In this inspection, there was an air leak in an unexpected place, and the loss of electricity bill was visualized. The nice thing about FLIR Si124 is that it displays the number of air leaks and the annual cost of loss in real time. This raises awareness of costs at the manufacturing floor. It also turned out to be difficult to detect by sound the location of an air leak that we couldn’t identify, leading to many new perceptions.

The number of leaks and the annual loss cost are displayed in real time.

FLIR Si124 makes it easy to identify leak points that were not otherwise detected.

Senior Managing Director Yamaguchi (Manufacturing Manager): At our manufacturing site, there are places such as burners where there is a lot of ambient noise. I was wondering how to actually find a leak with a one-handed camera. However, when I took a tour of the factory with FLIR Si124, I was surprised that leaks could be detected more accurately and easily than expected. We also fully detected air leaks from pipes far from the ceiling.

Inspect the air pipes on the ceiling.

Iwade Division Manager: When tracing a pipe with a camera, there is a small space due to the presence of surrounding equipment. However, the FLIR Si124 camera can easily get into these spaces. When I heard that the Si124 was less than half the size of a typical acoustic imaging camera, I immediately realized the benefits of its compact size.

FLIR Si124 is designed for convenient one-handed operation.

How the reflections are displayed.

Leaks can be identified by easily adjusting the Si124, such as changing the angle or changing the mode to improve visibility.

FLIR: What do you tell anyone thinking about using FLIR Si124?

Yagyu: Due to the importance of carbon neutrality in recent years, FLIR Si124 can find leaks with minimal burden on the manufacturing floor, thereby reducing power costs and helping to reduce CO2 emissions. .. seeing is believing! Would you like to check for air leaks at the factory? FLIR: Every time we join a customer for inspection, we find something new.

Mr. Yagyu: The most impressive thing this time was that I was able to find a leak in the pipe using Si124, which I could not find by sound alone. Normally, we treat reflected ultrasound as a target, but this time we had a unique experience of tracing the reflection to find the leak point. thank you very much.

Q & A

Q: How long is the average training period?

A: It takes about 5 minutes to operate and handle. Efficient use of the camera on-site OJT takes approximately 15-30 minutes (for 3 leak points).

Q: What is the target of diagnosis?

A: Piping for air, steam, nitrogen, etc. The type of air does not matter. However, the pressure must be above a certain level (minimum 0.3 Mpa or higher).

Q: How is the cost reduction effect?

A: Approximately 100,000 yen (72,000 yen) per year in the provisional calculation of leak point size 1.5 mm and pressure 0.7 Mpa [email protected] Mpa). If the leak point size is 12mm, the effect will be 600,000. [email protected] Mpa.

In most cases, a 30-minute tour of the manufacturer will find five or more leaks.

For demonstrations:

Demonstrations and on-site OJT are provided free of charge. If you are interested, please let us know the diagnosis target and piping pressure level. (Note that the camera cannot detect slow leaks.)

You can also use a thermal image camera to make a simple diagnosis of electrical equipment.Visit to find out more FLIR Si124 Industrial Acoustic Imaging Camera | Teledyne FLIR
