The housing includes an inlet and an outlet, and a fluid flow is communicated between the inlet and outlet. The body disposed inside the housing to form a fluid restriction for the fluid flow. The body includes an opening therethrough to divert a first portion of the fluid flow into a first fluid flow path; and a first surface to at least partially define the first fluid flow path. The body is adapted to move to control fluid communication through the first flow path based at least in part on at least one fluid property of the flow. ## Claims ### Claim 1 An apparatus usable with a well, comprising: a housing comprising an inlet and an outlet, wherein a fluid flow is communicated between the inlet and outlet; and a body disposed inside the housing to form a fluid restriction for the fluid flow, the body comprising: an opening therethrough to divert a first portion of the fluid flow into a first fluid flow path; a first surface to at least partially define the first fluid flow path; a hub comprising an axial bore that forms the opening and receives the first diverted portion of the fluid flow; and a first flange that extends radially away from the hub, the first flange comprising the first surface, and the first surface facing the housing to create the first fluid flow path in an axial gap between the first surface of the first flange and an upwardly facing surface of the housing, wherein the hub forms a second diverted portion of the fluid flow, the second diverted portion of the fluid flow being communicated outside of the opening to a second fluid flow path, the second fluid flow path being defined in part by a second surface of the first flange, wherein the first surface of the first flange is parallel to the second surface of the first flange, the body further comprising: a second flange to radially extend away from the hub, wherein the first flange directs the first diverted portion of the flow away from the hub, wherein the second flange directs a second diverted portion of the flow toward the hub, and wherein the body is adapted to move to control fluid communication through the first flow path based at least in part on at least one fluid property of the flow. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the first surface of the body faces away from the inlet. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the fluid flow is communicated radially outward from the opening to the outlet. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the outlet comprises a plurality of openings in the housing. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein: the first surface of the body faces away from the inlet; and the first fluid flow path extends between the first surface and the housing. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the second surface of the first flange faces the inlet and the first surface of the first flange faces away from the inlet. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein: the second flange forms a first segment of a second fluid flow path; the second flange directs the second diverted portion of the flow to the first segment of the second fluid flow path; the hub forms a second segment of the second fluid flow path; the hub directs the second diverted portion from the first segment of the second fluid flow path to the second segment of the second fluid flow path; the first flange forms a third segment of the second fluid flow path; and the first flange directs the second diverted portion from the second segment of the second fluid flow path to the third segment of the second fluid flow path. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the first fluid flow path has an associated first pressure loss that is a function of the at least one fluid property, the opening having an associated second pressure loss, and the body is adapted to move in response to a net force on the body created by the first and second pressure losses. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the net force moves the body to relatively restrict the axial gap of the first fluid flow path in response to the fluid flow having an associated relatively lower viscosity, and the net force moves the body to relatively open the axial gap of the first fluid flow path in response to the fluid flow having an associated relatively higher viscosity. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the pressure exerted by the fluid in the first fluid flow path acts in a direction on the body associated with increasing a cross-sectional flow area of the first fluid flow path, and the body comprises a second surface, the apparatus further comprising: a fluid sealing element to form a seal between the body and the housing to cause a pressure at the outlet to be communicated to the second surface of the body. ### Claim 11 (depends on 1) The apparatus of claim 1, wherein the housing has an outer profile adapted to mate with a profile associated with a radial port of a tubing string to control production of the flow from a region surrounding the tubing or control injection of the flow into the region. ### Claim 12 (depends on 1) The apparatus of claim 1, wherein the body is adapted to move to restrict fluid communication through the fluid flow path based at least in part on a viscosity of the flow. ### Claim 13 (depends on 1) The apparatus of claim 1 wherein a portion of the housing extends into the hub and circumscribes the inlet.
