Abstract
Implementations of an airflow capture hood flow control ring may include a flexible ring including a toroidal shape configured to couple around a base of an airflow capture hood. The ring may be configured to permit an airflow sensor coupled to the airflow capture hood coupled to an inlet to measure a flow of air into the inlet with at least 90% accuracy.
Claims16
An airflow capture hood flow control system comprising:
- an airflow capture hood comprising a collapsible base coupled around a grid, the grid configured to measure a passage of air through the airflow capture hood;
- and
- a flexible ring comprising a toroidal shape configured to removably couple around an outer surface of the collapsible base of the airflow capture hood;
- wherein the flexible ring is configured to removably couple around the outer surface of the base of the airflow capture hood through compression via an elastic bias force created by stretching then placing the flexible ring around the airflow capture hood.

An airflow capture hood flow control system comprising:
- an airflow capture hood comprising a pliable skirt coupled around a grid;
- and
- a ring removably coupled around an outer surface of a base of the pliable skirt;
- wherein a cross section of the ring has a diameter of substantially three inches;
- and
- wherein an inner circumference of the ring when the ring is not coupled to the airflow capture hood is less than an outer circumference of the outer surface of the base of the pliable skirt.
