An ultrasonic thickness gauge is a precise measuring instrument used to determine the thickness of a material from one side. This device uses ultrasonic sound waves to measure the thickness of various materials, including metals, plastics, ceramics, glass, and composites, without causing damage to the object being measured.
How Does It Work?
- The gauge works by emitting ultrasonic pulses through a transducer. These pulses travel through the material until they hit the opposite surface, then reflect back to the transducer. The gauge measures the time it takes for the pulses to return and calculates the thickness of the material based on the speed of sound in the specific material.
Ultrasonic thickness gauges are widely used in various industries, including:
- Manufacturing and Production: Ensuring the quality and uniformity of materials.
- Oil and Gas: Monitoring pipeline integrity and checking for corrosion.
- Aerospace: Inspecting aircraft components for wear and tear.
- Automotive: Measuring the thickness of parts and coatings.
- Marine: Checking the hull thickness of ships to prevent potential failures.
Key Features
- Non-Destructive Testing: Measures thickness without damaging the material.
- High Accuracy: Provides precise measurements, often down to a fraction of a millimeter.
- Versatility: Can be used on a wide range of materials.
- Portability: Handheld models allow for easy field inspections.
Benefits
- Safety: Helps identify potential weaknesses in materials before they lead to failures.
- Efficiency: Quick and easy to use, allowing for rapid inspections.
- Cost-Effective: Reduces the need for more invasive and costly testing methods.
- Reliability: Ensures the integrity and longevity of materials and structures.

Ultrasonic Wall Thickness Gauges go by other names such as wall thickness gauges, thickness testers, thickness meters, and thickness sensors. There are several methods to measure the wall thickness of materials such as steel, iron, copper, brass, glass, plastic and more using ultrasonic technology. As long as there is a smooth surface, an ultrasonic measurement can take place on any material that is solid and sonically conductive. Most applications for these thickness devices are too numerous to mention in one page. If the user is unsure if the Ultrasonic Thickness Gauges are the solution, then simply get in touch with us to see if we have a model that is able to meet the requirements. Non-destructive equipment is ideal for measuring the effects of corrosion or erosion on tanks, pipes, or any structure where access is limited to one side. Multiple echo options which work through paint will determine the metal thickness of a painted structure without having to remove the coating. Not all thickness gauges are the same, so it is best to make sure that the correct model has been selected so that a user will buy a thickness gauge in the Philippines that suits their frequent requirements.

The thickness of materials not mentioned in the above list can be programmed into the gauge. The following video shows how to program a thickness gauge to measure an unknown material. Although the EESIFLO video training module is over 10 years old, it is very useful for beginners to understand how to check measurements are correct using Ultrasonic Thickness Gauges.
How is an Ultrasonic Thickness Gauge Sensor Different from a Caliper?
If you take a look at the image below (caliper), it is possible to measure the thickness of materials such as steel and plastic but access is needed on both sides of the material so that a caliper can work. With an ultrasonic thickness gauge, it is only necessary to have access to one side of the material.
