Abstract

A flow control apparatus (10) having a flow monitoring system (12) capable of detecting and identifying flow present within the administration feeding set (14) loaded to the flow control apparatus (10) is disclosed. The flow control apparatus (10) comprises a single sensor (32) capable of detecting the presence or absence of fluid in the administration feeding set (14). A software subsystem (36) may be operatively associated with the single sensor (32) that is capable of identifying between upstream and downstream flow conditions present within the administration feeding set (14) loaded to the flow control apparatus (10).
