1. An air measuring station, comprising:
- (a) a station housing with an inlet opening and an outlet opening;
(b) a movable blade damper positioned in said station housing, said damper comprising a plurality of movable blades oriented in a first direction;
(c) a plurality of air flow sensing vanes positioned in said station housing downstream from said damper, said air flow sensing vanes being oriented in a second direction which is substantially orthogonal to said first direction; and
(d) said air flow sensing vanes being positioned less than 6 inches from said damper.

Abstract
An air flow measurement station with orthogonally mounted damper includes a station housing which encloses a damper with a plurality of movable damper blades. The damper blades are oriented in a substantially horizontal direction. The housing also encloses a plurality of air flow sensing vanes which are oriented in a second direction orthogonal to the first direction. With this orientation, the air flow sensing vanes can be positioned very close to the damper without creating dead air spaces such that reliable air flow sensing can be accomplished while keeping the station housing relatively compact.
