Ultrasonic thickness meter – D meter : To check the thickness of any metal.
Ultrasonic thickness meter (UTM) is used to perform non-destructive measurement (gauging) of the local thickness of a solid element (typically made of metal, if using ultrasound testing for industrial purposes) basing on the time taken by the ultrasound wave to return to the surface. This type of measurement is typically performed with an ultrasonic thickness gauge.
