In one aspect, an apparatus for use in a wellbore is disclosed, including: an inlet; an outlet; and a variable flow restriction configured to provide a predetermined constant pressure drop between the inlet and the outlet in response to a range of inlet flow rates. In another aspect, a method for providing a fluid flow within a wellbore is disclosed, including: providing the fluid flow to an inlet; restricting the fluid flow to provide a predetermined constant pressure drop between the inlet and an outlet in response to a range of fluid flow rates; and providing the fluid flow to the wellbore from the outlet.

1. An apparatus for use in a wellbore, comprising: an apparatus inlet;an apparatus outlet:a plurality of bones through which fluid flows between the apparatus inlet and the apparatus outlet, each of the plurality of bores having a bore outlet; anda plurality of movable members attached along a shaft between the apparatus inlet and apparatus outlet, the plurality of movable members being associated with the plurality of bores, with each movable member being associated with a respective bore, wherein the plurality of movable members are movable to alter a variable flow restriction between the apparatus inlet and apparatus outlet to provide a predetermined constant pressure drop between the apparatus inlet and the apparatus outlet in response to a range of apparatus inlet flow rates, wherein each bore provides a different pressure drop, and a primary pressure drop occurs at the movable member having a smallest difference between an outside diameter of the movable member and its respective bore outlet due to a position of the shaft. 2. The apparatus of claim 1, wherein the variable flow restriction is a plurality of associated flow restrictions created by the plurality of movable members. 3. The apparatus of claim 2, wherein each of the plurality of associated flow restrictions is configured to provide a target pressure drop in response to each of a plurality of discrete apparatus inlet flow rates. 4. The apparatus of claim 1, wherein the plurality of movable members is a plurality of movable disks. 5. The apparatus of claim 1, wherein the plurality of bores are between the apparatus inlet and the apparatus outlet. 6. The apparatus of claim 1, wherein the variable flow restriction includes a damping mechanism that urges the plurality of movable members towards the apparatus inlet. 7. The apparatus of claim 1, further comprising a locking mechanism configured to lock the plurality of movable members in a locked position to provide a minimal flow restriction between the apparatus inlet and the apparatus outlet. 8. A system for use in a wellbore, comprising: a pump with a fluid flow;a tubular associated with the fluid flow; anda pressure differential device associated with the tubular including: a device inlet associated with the fluid flow:a device outlet;a plurality of bores through which fluid flows between the device inlet and the device outlet, each of the plurality of bores having a bore outlet; anda plurality of movable members attached along a shaft between the device inlet and the device outlet, the plurality of movable members being associated with the plurality of bores, with each movable member being associated with a respective bore, wherein the plurality of movable members are movable to alter a variable flow restriction between the device inlet and device outlet to provide a predetermined constant pressure drop between the device inlet and the device outlet in response to a range of device inlet flow rates, wherein each bore provides a different pressure drop, and a primary pressure drop occurs at the movable member having a smallest difference between an outside diameter of the movable member and its respective bore outlet due to a position of the shaft. 9. The system of claim 8, wherein the variable flow restriction is a plurality of associated flow restrictions created by the plurality of movable members. 10. The system of claim 9, wherein each of the plurality of associated flow restrictions is configured to provide a target pressure drop in response to each of a plurality of discrete device inlet flow rates. 11. The system of claim 8, wherein the plurality of movable members is a plurality of movable disks. 12. The system of claim 8, wherein the plurality of bores are between the device inlet and the device outlet. 13. The system of claim 8, wherein the variable flow restriction includes a damping mechanism that urges the plurality of movable members towards the device inlet. 14. The system of claim 8, wherein the variable flow restriction includes a locking mechanism configured to lock the plurality of movable members in a locked position to provide a minimal flow restriction between the device inlet and the device outlet. 15. A method for providing a fluid flow within a wellbore, comprising: providing the fluid flow to a device inlet of an pressure differential device having the device inlet and a device outlet;moving a shaft having plurality of movable members between the device inlet and the device outlet, wherein the plurality of movable members are associated with a plurality of bores with each movable member being associated with a respective bore, wherein moving the shaft moves the plurality of movable members to alter a variable flow restriction between the device inlet and the device outlet to provide apredetermined constant pressure drop between the device inlet and the device outlet in response to a range of fluid flow rates at the device inlet, wherein each bore provides a different pressure drop, and a primary pressure drop occurs at the movable member having a smallest difference between an outside diameter of the movable member and its respective bore outlet due to a position of the shaft; andproviding the fluid flow to the wellbore from the device outlet. 16. The method of claim 15, further comprising creating a plurality of associated flow restrictions configured to restrict the fluid flow with the plurality of movable members. 17. The method of claim 16, further comprising providing a target pressure drop via each of the plurality of associated flow restrictions in response to each of a plurality of discrete fluid flow rates.
