Abstract
A testing system includes a single air collection box and a laminar flow system for obtain an airflow measurement. The single airflow box has air inlet and outlet ports at opposite ends. The laminar flow element has a laminar flow element inlet in fluid communication with the air collection box and a laminar flow element outlet sealed with the air outlet port of the air collection box. A blower in fluid communication with the laminar flow element outlet draws airflow into the air collection box through a unit under test and out of the air collection box through the laminar flow element. A pressure transducer senses the differential air pressure across the laminar flow element and enables a determination of the airflow rate.
