It consists of a vertical pillar and three or four cups. These cups capture the movement of air flows, and that’s how we get data about wind speed. But this is not the only type of instrument for measuring wind. WebMeasured across the cooling coil, typical A/C air flow is about 400 to 450 CFM per ton of cooling capacity. Typical air flow rates in CFM vary depending on the type of cooling system: 350 CFM per ton of cooling capacity is required for high-latent-heat HVAC applications. magic eye tube projects
