en.Wedoany.com Reported - API Measurement Services recently completed a 3D measurement project for the center axis of an extraction tower in the United States. Extraction towers are critical equipment in industries such as petroleum and chemicals, and their manufacturing and installation accuracy directly affects separation efficiency and operational safety. Traditional inspection methods struggle to capture comprehensive spatial data, while API utilized the Radian Pro laser tracker to achieve high-precision 3D measurements.

The API laser tracker emits laser beams to a target sphere to collect spatial coordinates of various parts of the tower, enabling detection of parameters such as tower straightness, verticality, shell roundness, and internal component installation accuracy. During measurement, the operator sets up the tracker at one end of the extraction tower and collects point cloud data along the inner wall, fitting the centers of each cross-section and calculating the straightness of the centerline. This solution supports high-precision measurements within a range of 160 meters at a data rate of 1000 Hz.

This measurement covered macroscopic geometric tolerances, installation accuracy of internal components, external interfaces, and manufacturing process control. By establishing a unified coordinate system, the API laser tracker provides data support for the digital delivery and lifecycle management of extraction towers. API was founded by Dr. Kam Lau in 1987 in Maryland, USA, and focuses on the research, development, and production of precision measurement sensors.
