Thickness Measurement (Ultrasonic)
Using ultrasonic echoes to measure material or wall thickness. The time delay between the initial pulse and back-wall echo is used with the material sound velocity to calculate thickness using: thickness = (velocity × time) / 2. Ultrasonic thickness measurement is non-destructive and requires access from only one side. It is the primary method for monitoring corrosion and erosion in vessels and piping.
