Abstract
An air flow sensing device comprised of rotatable spaced dampers, shafts to rotate the dampers, a counter-weight attached to a shaft biasing the dampers to a closed position with respect to air flow and pressure sensor means to determine the velocity of the air passing between and around the dampers when the dampers are in a closed position.
Claims21
Air flow sensing device comprising rotatable spaced dampers, means to rotate said dampers, counter-weight means attached to said means to rotate to bias said dampers to a closed position with respect to air flow and pressure sensor means to determine the velocity of the air passing between said dampers in said closed position.
