Abstract
An environmental monitoring and controlling system for a ventilated cage and rack system that monitors and measures air flow in the rack at either the rack or cage level. At the rack level, two pressure sensors are provided in a supply air system to accurately monitor the air flow rate into the rack. In addition, two pressure sensors may be provided in an exhaust air system to accurately monitor the air flow rate out of the rack. At the cage level, a cage may be equipped with a highly accurate pressure sensor, including a Venturi tube and thermistor, the monitor the air flow rate in a cage located at any cage position in the rack.
