Abstract
An ultrasonic thickness measuring apparatus comprises means for developing pulse counts responsive to the transit time of the ultrasonic search signal traversing the workpiece. The accumulated pulse count is displayed after each transit time interval and is used also to derive a correction factor which is inserted into the counter accumulating the counts during each time interval. This arrangement provides for the apparatus to almost immediately display a thickness value which nearly coincides with the final measurement value.
