Abstract

The Mobile Measurement Platform project develops a methodology to measure velocities in particulate flows. Its sensor package consists of two light obscuration sensors, each including a laser and photodiode spaced a distance x apart. Using two monochromatic laser beams as sensors connected to a computer via an A/D converter, custom analysis software incorporates a unique adaptation of a discrete cross correlation algorithm to calculate the time taken for the particulates to traverse the distance. The known sensor spacing divided by the software-derived time offset resulted in the flow velocity. To verify the system accuracy, the MMP was tested against a vane anemometer in four generated flows. The MMP values were repeatable and precise, but had an accuracy error of 22.2%.
