Need cost-effective retrofit dampers with flow sensors for commercial VAV boxes, as existing dampers have failed and funding for full replacement is unavailable.

Available retrofit dampers are residential-grade, lack flow rings, and are not suitable for commercial applications; finding commercial-grade retrofit dampers with integral flow sensors is difficult.
