摘要：
Systems and methods for determining when a fluid supply container of a blood processing apparatus becomes empty. The system uses a scale to monitor and detect when a fluid supply container is empty based on the rate of change of the container weight, and a controller receives a signal from the scale and controls the operation of a pump to stop pumping when the fluid supply container is empty.
