Theory Of Through Paint/Coatings
We developed first through paint/coating ultrasonic thickness gauge of Chinese make in 2006.
UM-1D has the ability to measure through and eliminate the thickness of paint or coatings on the surface of measured material.
In normal measurement mode, the time interval-T1 is between transmitted pulse and first back wall echo(coating thickness is included).
In through paint/coatings measurement mode, the time interval-T2 is between two successive back wall echoes( coating thickness is excluded)
