Abstract
A smartphone-operated air pressure meter and system includes an air pressure meter having a pair of input channels that are each connected to a pressure chamber and pressure sensor. A control unit is included with the pressure meter for receiving air pressure data and for transmitting the same. The system also includes an airflow balancing application that generates one or more application icons, and calculates airflow information. The airflow information can include the received pressure data alone, or pressure data that has been applied to a mathematical algorithm, along with environmental data.
