Description
The Xylem-McDonnell & Miller 306700 Paddle Kit is a flow sensing accessory used to detect water movement within piping and protect equipment from low or no-flow conditions. It includes interchangeable paddles sized for 1 inch and 6 inch pipe diameters, allowing proper adjustment to different line configurations. Installed in boiler and chiller circulation lines, it interacts with flow switches to signal operational status based on water movement. In hydronic equipment, HVAC systems use this kit to support safe system operation, improve flow monitoring accuracy, and maintain consistent circulation control in water-based heating and cooling circuits.
