Abstract:
1. A flowmeter for measuring and outputting total flow rate in terms of Q=velocity×area of a fluid in a pipeline without constricting the flow in the pipeline to permit measuring of flow in the pipeline, comprising: an exterior pipe having a diameter commensurate with the diameter of the pipeline; a pair of interior measuring tubes placed within said exterior pipe, said interior measuring tubes having a diameter less than that of said exterior pipe tube, wherein the area surrounding said two measuring tubes is equal to the combined area associated with said two measuring tubes each of said tubes including a sensor for measuring the flow of fluid through said interior measuring tubes in terms of velocity of said fluid times the area of said interior measuring tubes; and a processor coupled to said sensor for calculating and outputting the value Q=area×velocity/time for the combined flow through said interior measuring tubes and said exterior pipe based on sensed flow in said interior measuring tubes and the areas thereof, whereby the total flow in said pipeline is measurable in terms of the areas of the tubes and the velocity of the fluid therethrough without constricting the flow in the pipeline during the measurement process.
