Claims (1)
面と接触してシール性を保持するシールカツプが
設けられ、管内を通過する流体の圧力により管内
を走行しながら管の内径を計測する装置において
、 前記ピグ本体の外周部の各シールカツプ間に、
変形自在な保持カツプを管内面と非接触状態で設
け、 前記保持カツプの内側周部に少なくとも１個以
上の渦流センサを埋設保持して、管の内径を非接
触で計測する渦流距離計を構成するようにした ことを特徴とする管内径計測装置。[Scope of Claim for Utility Model Registration] A seal cup is provided on the front outer periphery and the rear outer periphery of the pig body to maintain sealing properties by contacting the inner surface of the pipe. In the device for measuring the inner diameter of the pig body, between each seal cup on the outer periphery of the pig body,
A deformable holding cup is provided in a non-contact state with the inner surface of the pipe, and at least one or more eddy current sensors are embedded and held in the inner peripheral part of the holding cup to constitute an eddy current distance meter that measures the inner diameter of the pipe in a non-contact manner. A pipe inner diameter measuring device characterized by:
