Ultrasonic Thickness Gauging (UTG) is a reliable, non-destructive method to accurately measure material thickness without cutting or damaging the surface. It plays a vital role in inspecting corrosion, erosion, and wear in critical industrial assets.
A Coating Thickness Gauge, also known as an Ultrasonic Thickness Gauge (UTG), is used to measure the thickness of various materials—metal, plastic, glass, rubber—using high-frequency sound waves. The instrument calculates thickness by measuring the time taken for sound waves to travel through the material and reflect back from the opposite surface.
UTG is a fast, safe, and accurate technique used extensively across industries to evaluate structural integrity, detect material loss, and plan maintenance schedules. It is especially effective where only one side of the component is accessible, such as storage tanks, pipelines, pressure vessels, and offshore structures.

Explore some of the most commonly asked questions about our Coating Thickness Gauge (UTG) service.
UTG is a non-destructive testing tool that uses ultrasound to measure the thickness of a material from one side without damaging it.
It’s used in oil & gas, marine, power, and construction industries for inspecting pipelines, vessels, tanks, and structures.
Yes, many UTG models can accurately measure through coatings without needing to remove them.
UTG works best with metals, plastics, and uniform solid materials. It’s not ideal for porous or multi-layered surfaces.
High-quality UTG devices offer accuracy within ±0.01 mm, depending on surface condition and material.
No, UTG is designed to measure thickness only. To detect internal flaws, methods like Ultrasonic Testing (UT) or Radiography are recommended.
