A Thermal Air Flow Meter is a device used to measure the rate of air flow in industrial systems. It works by using thermal power to determine the mass of air passing through an area, calculated as air velocity multiplied by air density. This data can then be used to accurately monitor and adjust air flow settings in commercial and industrial HVACHVAC systems. The benefits of a Thermal Air Flow Meter include improved energy efficiency, greater safety when operating machinery, and reduced maintenance costs.
