Abstract:
1. An apparatus for circumferentially measuring a tubular member, the apparatus comprising: first and second template members cooperably defining an aperture defining a cross-sectional reference shape of the tubular member, the first and second template members being configured to receive the tubular member in the aperture, at least one of the first and second members being adjustable such that the aperture is configured to be adjusted between open and closed positions, wherein at least one of the template members is capable of being at least partially closed to urge the tubular member to a cross-sectional shape corresponding to the reference shape of the aperture; and a measurement device configured to detect the relative position between the first and second template members, thereby measuring the relative adjustment of at least one of the members between the open and closed positions, a measurement of the measurement device being indicative of the cross-sectional size of the tubular member.
