	It defines an air capture hood (Balometer) as: ‘….lightweight collapsible assemblies used for the measurement of flow rates at supply and extract diffusers. An air flow hood captures the air from the diffuser and directs it past an integral array of pressure sensing points which (working on pitot tube principles) provide a direct measurement of flow rate. They give a direct reading, usually in l/s. The typical range is between 25 and 950 l/s. Typical instrument accuracies are in the range ± 3% of the indicated value.’		It defines an air capture hood (Balometer) as: ‘….lightweight collapsible assemblies used for the measurement of flow rates at supply and extract diffusers.
