The apparatus has a main flow channel; a chamber in fluid communication with the main flow channel, and having a flow control element movable between a first non-blocking position and a second blocking position for the fluid flow. The flow control element is movable in response to density of fluid in the chamber. The main flow channel has with pressure changing means causing a pressure differential in a fluid return conduit providing fluid communication between the chamber and a portion of the main flow channel, so that fluid in said chamber is recirculated back to the main flow channel when the main flow channel is open.
