Method of determining an airflow rate through a motor assembly of an air-moving device

Abstract

A method of determining a value of an airflow rate through a motor assembly of an air-moving device. The method includes measuring a first value of a first pressure at a first position in the motor assembly during operation. The method also include measuring, a second value of a second pressure at a second position in the motor assembly during operation of the motor of the motor assembly, where the second position is downstream of the first position. The method also includes performing a determination process based on the first value and the second value to determine the value of the airflow rate through the motor assembly.
