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 measures 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.
