Thickness measurement with drone (NDT)
Drone Eksperten specializes in NDT and inspection with drones, and as something completely new, we now also perform ultrasonic thickness measurement on metal surfaces.











Precise thickness measurement with drones
At Drone Eksperten, we offer advanced thickness measurement of metal surfaces using drones equipped with ultrasonic technology. This method allows for precise measurements in hard-to-reach or dangerous areas without the need for scaffolding or manual access. Our drones are equipped with the latest technology to ensure accurate and reliable results, making them ideal for inspecting tanks, pipelines and other industrial structures.

Always the right solution
How does ultrasonic thickness measurement with drones work?
Our drones use an ultrasonic probe that sends sound waves into the metal surface. When these waves are reflected back, the time it takes for them to return is measured, making it possible to calculate the thickness of the material.
This non-destructive testing (NDT) method is effective in detecting corrosion, erosion and other forms of material weakness without damaging the structure.
The drone’s flexible arm and laser guidance ensure precise probe placement, even in complex environments.

Benefits of ultrasound measurement with drone
Using drones for thickness measurement reduces the need for manual access to potentially dangerous or inaccessible areas. This increases safety for inspection personnel and minimizes operational downtime.
In addition, the advanced technology of drones allows for fast data collection and real-time analysis, ensuring that potential issues are identified early.
Our drones are also equipped with a smart coupling agent dispenser to ensure optimal ultrasonic transmission, as well as a cleaning module to prepare surfaces before measurement.

Drone Eksperten inspects quickly and accurately. We do everything from overflights, e.g. in connection with insurance cases, to checking the condition of roofs, gutters and buildings, to flying down into sewers and ship tanks. With drone inspection, we can help assess the extent of damage and capture necessary documentation.
Drones are particularly suitable for inspecting high-rise buildings, large buildings, wind turbines, bridges, chimneys, sewers, ship tanks, roofs and more. As it is a much safer and faster solution than sending a man high into the air with a crane and rope.
When we carry out drone inspections for our customers, we take great pride in proper planning and the quality of the material we record or the drone photos we shoot.
Frequently asked questions
How does thickness measurement with drones using ultrasound work?
Thickness measurement with drones uses an ultrasonic probe that sends sound waves into metal surfaces. When the waves are reflected back, the time it takes for them to return is measured, allowing the thickness of the material to be calculated. This method, also known as NDT (Non-Destructive Testing), provides precise measurements without damaging the structure.
What are the advantages of using drones for thickness measurement over traditional methods?
Drones make it possible to measure the thickness of metal structures in hard-to-reach and dangerous areas without the need for scaffolding or lifts. This saves time and money, increases safety for inspection personnel and reduces workplace downtime. The flexibility and technology of drones also enables them to collect data quickly and efficiently.
What types of structures can be inspected with drones' ultrasonic thickness measurement?
Drone ultrasound technology is ideal for inspecting metal structures such as tanks, pipelines, ships, bridges and industrial machinery. We use drones to measure the thickness of metal surfaces in both outdoor and indoor environments where access would otherwise be difficult.
Is the thickness measurement with drones accurate enough to identify corrosion or material defects?
Yes, ultrasonic thickness measurement is one of the most accurate methods to identify corrosion, erosion or other material weaknesses. The drones ensure that the measurements are taken with high precision, giving an accurate picture of the structure so that any problems can be detected in time.
How do you ensure that the ultrasonic probe is correctly positioned on the structure during the inspection?
The drones are equipped with a flexible arm and advanced laser guidance, which allows the ultrasonic probe to be positioned precisely on the surface. This ensures that measurements are accurate even in difficult and complex environments where manual access would be difficult or dangerous.
How can I order a thickness measurement with drones for my inspection?
You can contact us for a no-obligation conversation about your inspection needs. We customize solutions to suit your specific task and provide you with an accurate report based on our measurements. We make sure you get fast and reliable results that help optimize your operations and maintenance.
