A flow control device particularly useful as a drip irrigation emitter includes a housing having a housing including a plurality of inlet openings defining a plurality of filtering inlet passageways to communicate with a pressurized fluid, an outlet opening, and a connecting passageway connecting the inlet openings to the outlet opening, and a pressure-deformable elastomeric membrane having a edge overlying the inlet openings and deformable to change the effective cross-sectional areas thereof in a dynamic manner in response to the pressure of the pressurized fluid.
