Ultrasonic thickness gauges measure material and wall thickness non-destructively using sound waves, often with access required from only one side of the component. They are widely used for remaining-wall-thickness checks, corrosion monitoring, maintenance inspection and dimensional verification on pipes, tanks, vessels, plate and engineered components.

Typical applications

• Pipe and pressure-vessel wall thickness measurement
• Corrosion and erosion monitoring
• Tank, plate and structural component inspection
• Manufacturing and maintenance quality control
• Thickness measurement where the opposite surface is inaccessible

Choosing a gauge

Key factors include the material being measured, expected thickness range, required resolution and accuracy, component geometry, probe type and whether measurement through paint or coatings is required. Selected models also support specialised probes for thin walls, coarse-grain materials and elevated-temperature applications.
