Abstract
Official abstract text for this publication.
A vortex generator for use in a flowtube of a meter is provided. The vortex generator includes a plurality of raised elements on an inner surface of a flowtube. The plurality of raised elements are positioned on the inner surface of the flowtube upstream of a widening of the flowtube. The presence of the plurality of raised elements improves boundary layer adherence.
First claim
Opening claim text (preview).
That which is claimed is: 1. A vortex generator comprising a plurality of raised elements on an inner surface of a flowtube of a meter, the flowtube having a first portion having a uniform cross-section and a second portion, after the first portion having an increasing cross-section in a direction of flow and the plurality of raised elements being positioned on the inner surface of the first portion of the flowtube upstream of the increasing cross-section of the flowtube, wherein presence of the plurality of raised elements improves boundary layer adherence. 2. The vortex generator of claim 1 , wherein the plurality of raised elements on the inner surface of the flowtube promote a turbulent flow in the flowtube. 3. The vortex generator of claim 1 , wherein the plurality of raised elements comprise a plurality of shapes molded into a plastic inner surface of the flowtube. 4. The vortex generator of claim 3 , wherein the plurality of shapes comprise a plurality of V shapes. 5. The vortex generator of claim 1 , wherein the plurality of raised elements comprise a plurality of shapes positioned and affixed on a plastic inner surface of the flowtube. 6. The vortex generator of claim 1 , wherein the meter comprises a gas meter. 7. A flowtube comprising: a first portion having a uniform cross-section and a second portion, after the first portion, having an increasing cross-section in a direction of flow in the flowtube at an end thereof, the second portion having the increasing cross-section providing an increased area of flow to decelerate the flow in the flowtube of a meter; and a vortex generator comprising a plurality of raised elements on an inner surface of the flowtube upstream of the second portion having an increasing cross-section, presence of the plurality of raised elements improving boundary layer adherence in the flowtube. 8. The flowtube of claim 7 , wherein the plurality of raised elements on the inner surface of the flowtube promote a turbulent flow in the flowtube. 9. The flowtube of claim 7 , wherein the plurality of raised elements comprise a plurality of shapes molded into a plastic inner surface of the flowtube. 10. The flowtube of claim 9 , wherein the plurality of shapes comprise a plurality of V shapes. 11. The flowtube of claim 7 , wherein the plurality of raised elements comprise a plurality of shapes positioned and affixed on a plastic inner surface of the flowtube. 12. The flowtube of claim 7 , wherein the meter comprises a gas meter. 13. A meter comprising: a flowtube having a first portion having a uniform cross-section and a second portion, after the first portion, having an increasing cross-section in a direction of flow in the flowtube an end thereof, the second portion having the increasing cross-section providing an increased area of flow to decelerate the flow in the flowtube; and a vortex generator comprising a plurality of raised elements on an inner surface of the flowtube upstream of the second portion having an increasing cross-section, presence of the plurality of raised elements improving boundary layer adherence in the flowtube. 14. The meter of claim 13 , wherein the plurality of raised elements on the inner surface of the flowtube promote a turbulent flow in the flowtube. 15. The meter of claim 13 , wherein the plurality of raised elements comprise a plurality of shapes molded into a plastic inner surface of the flowtube. 16. The meter of claim 15 , wherein the plurality of shapes comprise a plurality of V shapes. 17. The meter of claim 13 , wherein the plurality of raised elements comprise a plurality of shapes positioned and affixed on a plastic inner surface of the flowtube. 18. The meter of claim 13 , wherein the meter comprises a gas meter.
