ABSTRACT:
A multiple flow metering system includes first and second vortex flowmeters for measuring a flow of a fluid. The first vortex flowmeter includes a first bluff body having a leading edge and a shape for inducing a first stream of vortices in the fluid as a function of the flow at a wavelength .lambda.. The first vortex flowmeter also includes a first vortex sensor which generates a first output based on a frequency of the first stream of vortices. The second vortex flowmeter includes a second bluff body having a leading edge and a shape for inducing a second stream of vortices in the fluid as a function of the flow at the wavelength .lambda.. The second vortex flowmeter also includes a second vortex sensor which generates a second output based on the frequency of the second stream of vortices. The leading edge of the second body is spaced from the leading edge of the first body by 1.15.lambda. to 2.0.lambda..
