The instruction card gives clear directions on how to hook up the components to measure duct air velocity, supply grille velocity, return grille velocity static pressure, and, if needed, furnace draft and air filter test.
Powered flow hoods have proven to also be successful in the measurement of supply airflows in which the nonuniformity of air entering the flow hood due to supply grille geometry is counteracted by the use of the fan coupled with high-airflow-resistance flow straighteners and measurement methods (Walker and Wray 2003; Wray et al.
Flow-setting dampers at the manifold, not the supply grille. Keeping the air velocity high and the airflow straight as it leaves the supply grille is important for good air mixing.
Figure 11 shows the selected air distribution design with ceiling supply grilles and four return grilles.
