Abstract
A vortex flowmeter has an elongated vortex generator in the flow passage of a body and transverse to the direction of flow. A first wing is located in the flow passage downstream of the generator and a second wing is located downstream from the first wing. A sensor is associated with each wing to provide a signal responsive to movement of the wing, and the signals are combined to have external noise components of the signals cancel each other. In one embodiment, the wings are shorter than a vortex street wavelength, and the wings are separated by a distance that is an odd multiple of the half wavelength. In another embodiment, the wings each have a length of about one wavelength.
