Abstract

PURPOSE: To perform a continuous measurement for the thickness of an insulating layer with no influence from noise waves by measuring, by means of a counter, a time interval between a reflection wave pulse from the interface between a cooling bath and an insulating layer and the reflection wave pulse from the interface between the insulating layer and an electric wire.
