MEASUREMENT DEVICE

摘要

A measurement device provides coordinates for a specified location and position on the exterior surface of a vessel (14), including a base (20) adapted to contact the exterior surface of the vessel (14); a rail (30) extending upwardly from the base (20), the rail (30) including a measurement scale (42); a head (32) slidably supported by the rail (30); the head (32) including a clamping mechanism (40) used to releasably secure the head (32) to the rail (30); and a laser (64) carried by the head (32) for projecting an image on the exterior surface of the vessel (14). The device quickly measure s both the radial position and the angular position of an indicated location relative to the axis of the nozzle (12), and the skew of a transducer probe (111) which provided the indicated location.
