Abstract
A system includes a first shedder that is at least partially disposed in a fluid conduit and that generates vortices within the fluid conduit, a first flow sensor system that is responsive to the vortices generated by the first shedder and a second flow sensor system that is responsive to the vortices generated by the first shedder. The system further includes a second shedder that is at least partially disposed in the fluid conduit, that generates vortices within the fluid conduit, and that is separated from the first shedder by a distance. A third flow sensor system is responsive to the vortices generated by the second shedder.
Claims20
A system, comprising:
- a first shedder that is at least partially disposed in a fluid conduit and that generates vortices based on a fluid flow within the fluid conduit;
- a first flow sensor system that is responsive to the vortices generated by the first shedder;
- a second flow sensor system that is responsive to the vortices generated by the first shedder;
- a second shedder that is at least partially disposed in the fluid conduit, that generates vortices based on a fluid flow within the fluid conduit, and that is downstream of the first shedder and separated from the first shedder by a distance;
- and
- a third flow sensor system that is responsive to the vortices generated by the second shedder.
A method, comprising:
- generating vortices in a fluid flow within a fluid conduit using a first shedder that is at least partially disposed in the fluid conduit;
- inducing a response in a first flow sensor system based on the vortices generated by the first shedder;
- inducing a response in a second flow sensor system based on the vortices generated by the first shedder;
- generating vortices in the fluid flow within the fluid conduit using a second shedder that is at least partially disposed in the fluid conduit, the second shedder being downstream of the first shedder and separated from the first shedder by a distance;
- and
- inducing a response in a third flow sensor system based on the vortices generated by the second shedder.
A system for monitoring a fluid flow rate within a fluid conduit, comprising:
- a first shedder that is at least partially disposed in a fluid conduit;
- a first flow sensor system that is responsive to vortices generated by the first shedder in a fluid flow within the fluid conduit;
- a second flow sensor system that is arranged in parallel relative to the first flow sensor system, and that is responsive to the vortices generated by the first shedder;
- a second shedder that is at least partially disposed in the fluid conduit, and that is downstream of the first shedder and separated from the first shedder by a distance, the distance being a multiple of a diameter of the fluid conduit;
- and
- a third flow sensor system that is responsive to the vortices generated by the second shedder in the fluid flow within the fluid conduit.
