Abstract:
1. A method of determining an average flow of a flowing stream with a laser velocity meter comprising the steps of: repeatedly changing a laser's position whereby the laser's position is repeatedly changed with respect to a lens' position so that a laser's light focus occurs at one of many points so that a velocity of the flowing stream can be measured at several different points in the flowing stream to obtain a better estimate of average flow, wherein the step of repeatedly changing the laser's position includes the step of: repeatedly changing the laser's position sideways with respect to a lens' position while moving it perpendicular to a beam path so that the laser's light focus occurs at one of many points along the width of the flowing stream, so that the velocity of the flowing stream can be measured at several different points along the width of the flowing stream, in order to obtain a better estimate of average flow.
