Abstract
Studied the measurement method of ratio of curvature and diameter for elbow-pipe sensor of the ZWL intelligence elbow-pipe flowmeter
a new measuring method called the three coordinates measurement
which uses the three coordinates measurement machine to measure is brought forward.Set up the mathemtical model of solving ratio of curvature and diameter
measured three dimension coordinate points by the three coordinates measurement machine
completed software of ratio of curvature and diameter by MATLAB
calculation of ratio of curvature and diameter is finished.This measurement method is able to present characters of elbow-pipe shape direcfly
