Abstract: Intelligent wireless test and flow balance system that has a wireless system with data inputs and physical outputs for automatic HVAC test and balance. A wireless physical output device for temporarily rotating air dampers or water valves is utilized to control the output of the air dampers or water valves. The flow and output node system is battery powered allowing for placement in remote locations. The system also includes a capture hood that utilizes magnets to hold itself while allowing data to be captured. An airflow measurement device that uses a pass-through measurement technique, this airflow measurement device may be placed within or outside the capture hood. A unique adapter allows an electric motor to be temporarily attached to a damper or valve shaft. A wireless node network that allows for one or more nodes, such as flow and output nodes to be connected in a hierarchical or mesh network.
