The johnson controls single duct units along with all vav family model types of johnson controls are manufactured and assembled with a patented multi point center averaging airflow sensor called the flowstar sensor. The flowstar sensor provides a signal to the johnson controls controller enabling it to quietly and precisely measure airflow. They are specifically designed for precise air delivery throughout the entire operating range regardless of the installed inlet conditions. It is designed to control the air flow to a specific area called a zone.
