Abstract
An airflow sensor system for an air duct including a damper positioned therein is provided. The controller is configured to determine, via a first pressure sensor, a first airflow measurement based on a first one or more pressure measurements. The controller is further configured to determine, via a second pressure sensor and a damper position sensor, a second airflow measurement based on a second one or more pressure measurements and one or more damper position measurements. The first airflow measurement and the second airflow measurement have a first uncertainty value and a second uncertainty value associated therewith. The controller is further configured to determine an estimated airflow based on weighted values of the first airflow measurement and the second airflow measurement. The weighted values are based on the airflow measurements and the uncertainty values associate therewith.
