ABSTRACT:
A device for measuring the volume of air flowing into or out of an air conditioning duct. The device includes a hood having a top end adapted to cover the air conditioning duct to provide channeling of the air flow into an air flow measurement housing. The air flow measurement housing includes an air flow channel and a manometer for measuring the velocity pressure of air flow through the channel. Movable vanes are provided for varying the cross-sectional area of the air flow channel. Measurement of the air flow volume is accomplished by varying the cross-sectional area of the air flow channel to achieve pre-selected velocity pressure values. Scales are provided which indicate air flow volume based on calculation of the air flow volume at the particular cross-sectional area and air velocity pressure. A series of scales is provided corresponding to a series of increasing velocity pressures so that a wide range of air flow volumes may be determined.
