Abstract
An air pressure measuring ventilation system, comprising: at least one duct; at least one motorized exhaust fan; and one or more air pressure sensors. The at least one motorized exhaust fan may draw air through the at least one duct. The one or more air pressure sensors may be placed on a side of the at least one duct such that an air pressure is measured as the air is drawn through the at least one duct, such that a plurality of air pressure measurements are generated. The one or more air pressure sensors may be substantially flush with an interior side of the at least one duct and do not obstruct the air as the air is drawn through the at least one duct.
