Three coordinates measuring method of elbow-pipe sensor's ratio of curvature and diameter

LI Chao-na~1,HUO Ping~1,SONG Jian-hua~2(1.College of Mechanical Engineering,Hebei Polytechnic University,Tangshan 063009,China;2.Tangshan Intelligent Instrument Co.,Ltd,Hebei Polytechnic University,Tangshan 063000,China)  
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,better precision and easier to operate.
