Abstract:
1. A system for ascertaining absolute fluid flow in a passage way, comprising: a configuration of known cross section, said configuration to be inserted into a fluid flowing in said passage way, said configuration placed to intersect said fluid flow at approximately ninety degrees to the direction of said fluid flow and sized to span approximately the entire width of said passage way; a carriage to support said configuration, said carriage enabling said configuration to move vertically in a fixed plane within said passage way with approximately no lateral deviation; at least one instrument in operable communication with said configuration, wherein said instrument records measurements of force applied to said configuration, said force resultant at least from said fluid flow, and wherein said recorded measurements are taken at intervals while moving said configuration in a vertical plane approximately perpendicular to the direction of said fluid flow; at least one data recorder for recording said measurements; at least one specially configured computing device for integrating said recorded measurements and employing at least one first algorithm incorporated in software contained on computing device readable media accessible by said specially configured computing device that employs said software to process said integrated recorded measurements to convert said integrated recorded measurements into at least one value of absolute flow; and at least one control apparatus, wherein said control apparatus is in operable communication with at least said carriage, said data recorder and said specially configured computing device to facilitate operation of said system.
