1. An enteral feeding system (10) comprising:

  • an administration feeding set (14) forming a conduit (23) adapted for fluid flow communication therethrough, the administration feeding set (14) including a magnetically-susceptible, non-magnetic metallic component (21); and

    a flow control apparatus (12) operatively associated with said administration feeding set (14) for establishing fluid flow through said conduit (23), said flow control apparatus (12) further including a sensor arrangement (33) comprising a back-biased sensor (34) and magnet (36), said sensor arrangement (33) generating a magnetic flux for sensing the presence of said component (21) properly received on the flow control apparatus (12), wherein said component (21) changes the magnetic flux and said change in magnetic flux is detectable by said sensor (34) when said administration feeding set (14) is properly engaged to said flow control apparatus (12).
