A finned tube is a heat transfer device consisting of many parallel metal fins commonly used for heat dissipation and cooling applications. Finned tubes increase the surface area of the pipe, thus increasing the heat transfer efficiency. Finned tubes are commonly used in applications such as air coolers, automotive radiators, condensers, and evaporators. They are also used in industrial heaters and refrigerators to increase heat transfer surface area and improve efficiency.
Finned tube is a kind of new, wear-resistant, efficient heat exchange material, is a kind of energy-saving heat exchange element, it uses high-frequency power source as heat source, the steel strip, steel pipe heating at the same time, so that the fusion welding together into one, with high heat exchange efficiency, large cooling area, long service life, adapt to a wide range of temperature, high pressure characteristics, it can also be made of a variety of materials, Excellent heat transfer, durability, heat resistance and corrosion resistance. Widely used in waste heat recovery, petrochemical, power plant boiler, economizer, bus, industrial and civil construction heating, refrigeration, medical drying, wood drying, food drying system and other industries.
The main business scope is various heaters, waste heat boilers, pressure vessels, supportingair preheaters, air coolers, furnace accessories and accessories, and provide equipment installation, with EPC ability of projects. At present, our customers have covered all large and medium-sized petrochemical enterprises in China and established long-term strategic cooperative partnership with them. Products are exported to Southeast Asia, Middle East, and other regions.

Your Questions Answered—Answers to Live Questions Asked During Our Webinar with GeoSLAM
Last Wednesday, November 9, we held a webinar titled “How to Make Survey-Grade 3D Models with the Elios 3 and GeoSLAM Connect.†It was one of our most attended webinars to date, with nearly 1,000 signups and more questions than ever before. Due to time constraints, we couldn’t answer every question during the live session, so we’ve compiled this guide to address all the queries we missed. You can scroll down to see all the answers or use the menu below to jump to specific categories.
Here’s a quick navigation menu:
- Questions related to accuracy and precision testing
- GeoSLAM and data processing questions
- Elios 3 operations and best practice questions
- LiDAR-related questions
- LiDAR data collection questions
Want to learn more about the two tests we shared in the webinar?
In the session, we presented results from two key tests on the Elios 3's LiDAR data processed through GeoSLAM Connect. You can read more in these white papers:
- Testing Global Accuracy and Georeferenced Accuracy in 3D Mapping with the Elios 3 and GeoSLAM Connect
- Testing Local Accuracy and System Precision in 3D Mapping with the Elios 3 and GeoSLAM Connect

**Questions Related to Our Accuracy and Precision Testing**
Q: Is the accuracy reported only valid when using silver reference pads?
A: No, the silver targets are used for consistency between scans but aren’t required to achieve the stated accuracy. The results apply even without them.
Q: Can accuracy be improved by using a more accurate scanner?
A: Future software and hardware upgrades may improve performance. The latest Ouster sensor offers better precision, and future GeoSLAM updates could also enhance accuracy.
Q: Is the error due to flight or device limitations?
A: It’s a combination of factors, including sensor quality, flight technique, registration method, and target selection.
Q: How is accuracy based on one flight if three were done?
A: Each flight covered the entire asset and was analyzed separately for accuracy.

**GeoSLAM and Data Processing Questions**
Q: Can I create a textured mesh from the data?
A: Not directly in GeoSLAM, but other tools can convert point clouds into meshes.
Q: Can I export timestamped trajectory and point cloud for TerraMatch?
A: Yes, both can be exported and reprocessed in GeoSLAM Connect.
Q: Can I add tags or picture recognition to the 3D model?
A: Tags are under consideration, but no timeline has been set yet.
Q: Can I export to Autodesk Recap Pro after merging flights?
A: Yes, you can export to E57 or use GeoSLAM Draw to mesh or export to CAD formats.
Q: How many pre-coordinated points are needed for displacement tracking?
A: At least four targets are recommended for accurate alignment.
Q: Can I get colorized point clouds?
A: Yes, they are colorized based on LiDAR intensity, not real RGB.

**Elios 3 Operations and Best Practice Questions**
Q: How can I get training on using the Elios 3?
A: Flyability offers AAIM training that covers various use cases. Learn more here.
Q: Can I use a tether system for recovery?
A: We don’t recommend it due to risk of entanglement, except in specific environments.
Q: How does the drone perform underground?
A: It works well in mines and can operate from -3,000m to 5,000m altitude.
Q: What’s the max range with the Range Extender?
A: Up to 500 meters in straight lines, but symmetrical environments may affect performance.
Q: Can I integrate other sensors into the Elios 3?
A: Currently not available, but we’re exploring new integrations.
Q: Can I capture images with the drone?
A: Yes, the Elios 3 captures 12MP images with strong lighting.
Q: Can I buy the drone without the LiDAR?
A: Not at the moment, but the LiDAR can be removed if not needed.

**LiDAR Questions**
Q: What is the maximum distance for the LiDAR?
A: It can detect up to 30 meters, but we recommend flying within 10 meters for high accuracy.
Q: What file format does the LiDAR use?
A: The raw format is .bag, but you can export to .las, .laz, .ply, .txt, and .p57.
Q: How many points per second does the LiDAR generate?
A: 300,000 points per second.
Q: Is the LiDAR single or multi-return?
A: It’s multi-echo and returns the strongest signal.

**LiDAR Data Collection Questions**
Q: How do I control the flight speed for consistent data?
A: Use Assist mode (ATTI), which limits speed to 1.5 m/s for optimal data capture.
Q: How can I avoid SLAM errors in symmetrical pipes?
A: Keep visible features like bumps or corners in the LiDAR field of view. Flying sideways may help.
Q: Can I control the scanner’s field of view in GeoSLAM Connect?
A: This feature hasn’t been explored yet.
