Abstract
An apparatus and method for determining a velocity of propagation and the thickness of different substances such as pipe walls utilizes a transducer connected to an A-scan. This material is placed in a holder between the transducer and a reflecting surface, the holder containing a fluid having a known velocity of propagation. The transducer converts high voltage electrical pulses produced by a generator into ultrasonic vibrations and also converts echo signals received from the reflecting surface and the material back into electrical pulses. A display device connected to the transducer displays these pulses and their exact position on the display device is used to determine the velocity of propagation and the thickness of the material.
