Description
The Noritz EPAD001 Water Flow Sensor is a flow detection component used in tankless water heater systems to monitor incoming water demand and signal the control board when hot water is required in HVAC systems. It work by sensing water movement through the unit and enabling the burner ignition sequence only when sufficient flow is detected, ensuring safe and on-demand operation. It plays a key role in coordinating system activation, efficiency, and safety by preventing dry firing and unnecessary burner operation.
