径計測用装置。 A device for measuring the inner diameter of a pipe using ultrasonic waves, which comprises: a drive mechanism that sequentially rotates one or more ultrasonic transmitters/receivers at equal angles in the radial direction of the pipe; and the above-mentioned ultrasonic transmitter/receiver. It has a mechanism for moving the device in the radial direction of the tube, receives echoes from the tube wall of the ultrasonic waves transmitted from the ultrasonic transmitter, measures the time from transmission to reception, and records this. A device for measuring a pipe inner diameter, further comprising a personal computer for processing this record as necessary.
