Abstract

A remote zone balancing damper and air flow sensor system comprising a differential pressure air flow sensor, a damper having an actuator, a remote terminal connected to the air flow sensor and the actuator, the remote terminal disposed a predetermined distance from the duct, the air flow sensor and damper mounted in a duct, and a detachable controller that is connectable to the remote terminal, the detachable controller configured to receive a signal from the remote terminal and to provide power to the actuator and thereby position the damper according to the calculated air flow.

Claims

exact text as granted — not AI-modified

1 . A remote zone balancing damper and air flow sensor system comprising:
 a differential pressure air flow sensor;   a damper having an actuator;   a remote terminal connected to the air flow sensor and the actuator, the remote terminal disposed a predetermined distance from the duct;   the air flow sensor and damper mounted in a duct; and   a detachable controller that is connectable to the remote terminal, the detachable controller configured to receive a signal from the remote terminal and to provide power to the actuator and thereby position the damper according to the calculated air flow.   
     
     
         2 . The system as in  claim 1 , wherein the controller comprises an energy source for energizing the actuator. 
     
     
         3 . The system as in  claim 1 , where in the controller comprises a visual display. 
     
     
         4 . The system as in  claim 3 , wherein the controller comprises:
 a processor connected to the visual display;   a pressure transducer connected to the air flow sensor and to the processor; and   the processor using a signal from the pressure transducer to calculate an air flow rate, the air flow rate displayable on the visual display.   
     
     
         5 . The system as in  claim 1 , wherein the air flow sensor is disposed upstream of the damper.
