The experimental and emulational analysis of the interface position and molecule diffusion across two aqueous liquids in pressure-driven flow in "Y-sensor" were introduced. Experiments and numerical simulation on the interface location were conducted under the condition of keeping the flow rate at one inlet 20 mL/h and the flow rate at the other inlet 2, 4, 8, 12, 16, 20 mL/h respectively. The numerical simulation on the interface diffusion was verified by visualized experiments when the flow rates at the inlets are both 2 mL/h. Results show that the ratio of stream width and the ratio of flow rates are almost equal in "Y-sensor"; the diffusion extent at the interface between two streams scales as one third power of the down stream distance.
