System and method for measuring air flow at multiple points of an air channel

摘要

A device measures air flow at multiple points in an air channel. The device includes a metering plate that has multiple passages through the metering plate. The metering plate is adapted to be positioned across the air channel in an orientation that places two or more of the multiple passages at two or more respective locations within the air channel. The metering plate is also adapted to receive two or more flow meters at the two or more passages, respectively. In addition, the metering plate is configured so that respective air flow velocities at the two or more locations when the metering plate is positioned across the air channel substantially matches air flow velocities at the two or more locations when the metering plate is not positioned across the air channel. An example embodiment includes holders such as sockets that keep the flow meters fixed in the metering plate with regard to pitch and roll.
