Abstract

This PSM 1 report presents an investigation into the application of combination of laser and optical sensor to measure velocity of solid particle, flow in a conveying pipe. The merit of this method is, it can measure solid particle in a mixture with clear liquid. In order to measure velocity, two arrays of sensors are placed upstream and downstream on the pipe. The output of the downstream sensors will be replica of the upstream sensors. The sensor arrangement use is orthogonal.output from both upstream and downstream sensors will cross correlated .From the result of the cross-correction,the peak of the cross correlation graph represented the time for the object to move from upstream to downstream. The velocity is obtained by simply dividing the time and the distance . between upsrteam and downstream.
