A time based flow controller for incompressible fluid includes at least one reservoir 1, the volume of each reservoir 1 changing in a cycle, at least one inlet valve 13, each inlet valve 13 opening/closing an inlet of a corresponding reservoir 1, at least one outlet valve 3, each outlet valve 3 opening/closing an outlet of a corresponding reservoir 1, and a controller for controlling the number of opening/closing loops of the inlet valve 13 and the outlet valve 3 per unit time and/or mass/volume of the incompressible fluid stored and discharged at the reservoir 1 per unit opening/closing loop of the inlet valve 13 and the outlet valve3 , the controller opening the inlet valve 13 to allow the incompressible fluid to flow into the reservoir 1 when the outlet valve 3 is in a closed state, and thereafter opening the outlet valve 3 to allow the incompressible fluid to flow out from the reservoir 1 when the inlet valve 13 is in a closed state, so that the controller may control the mass/volume flow rate of the outflow incompressible fluid from the reservoir 1. |
