摘要：
A flow control device may include a body having at least two flow paths configured to convey the fluid. The flow paths may be hydraulically isolated from one another in the body and at least one of the flow paths may be selectively occludable. In certain arrangements, a filtration element may be positioned upstream of one or more of the plurality of in-flow control devices. The flow paths may utilize features such as chamber and openings in order to impose a specified pressure drop on the fluid flowing there across.
