ULTRASONIC TRANSDUCING APPARATUS FOR MEASURING PIPE THICKNESS AND APPARATUS FOR MEASURING FLOW VELOCITY USING THE SAME

摘要

The present invention relates to an ultrasonic transducing apparatus which includes: a wedge attached to an external wall of a pipe and having at least two or more surfaces except a surface in contact with the pipe; an ultrasonic transducer attached to a first surface among at least two surfaces of the wedge and transmitting an ultrasonic signal into the pipe through the wedge; and a pipe measurement unit measuring a thickness of the pipe based on a time difference of two or more reflected waves where the ultrasonic signals incident from the ultrasonic transducer respectively are reflected from an inner wall of a second surface among the external wall of the pipe and an interface of the wedge, an inner surface of the pipe and an interface with an inner fluid, and two surfaces of the wedge to be retransmitted to the ultrasonic transducer.
