Abstract
A fluid-flow measuring apparatus is made of an enclosure housing that supports a plurality of flow-receiving tubes, each one of which has a plurality of apertures the either face substantially towards the source of fluid flow or away therefrom, a dispersing blade with a surface located in a plane that is parallel to a plane that is tangent to the surface of at least one of the plurality of flow-receiving tubes, a hub intersecting at least one of the plurality of flow-receiving tubes, and a facilitator structure that separates at least two of the plurality of flow-receiving tubes.
Claims20
A fluid-flow measuring apparatus, comprising:
- an enclosure housing;
- a tubular flow sensor that receives fluid flow through an aperture therein;
- a hub intersecting the tubular flow sensor;
- and a facilitator structure comprising:
- a section interconnecting a first portion of the enclosure housing to a second portion of the enclosure housing opposite the first portion, and
- two walls extending downwardly from the section, wherein the section and the two walls bound an area that is shielded from flow by the facilitator structure,
- wherein the tubular flow sensor and the hub are each disposed outside of the area shielded by the facilitator structure.
A fluid-flow measuring apparatus, comprising:
- an enclosure housing;
- a tubular flow sensor that receives fluid flow through an aperture therein;
- a hub intersecting the tubular flow sensor, wherein the hub comprises at least one plate therein;
- and a facilitator structure comprising:
- a section interconnecting a first portion of the enclosure housing to a second portion of the enclosure housing opposite the first portion,
- wherein the tubular flow sensor and the hub are disposed outside of the facilitator structure and interconnected to the facilitator structure via a third portion of the enclosure housing.
