Studies of the measurement of the thickness for metal non magnetic using manual method (calipers) and ultrasonic thickness have been made by researcher. The weakness of the both method were the accurateness of data for hard reading process and the price of materials more expensive. Development of the sensor technology allows to pubricate of metal thickness detector which can solution for the di…
