A radial diffuser includes an inlet section, outlet section, diffuser wall, and movable diffuser hub. The inlet section has a cylindrical shape and a circular cross section. The diffuser wall includes an inner surface defining a fluid flow path which is non-linear, and includes a convex curved section and a concave curved section. The convex curved section is adjacent to the inlet section and has a convex curvature. The concave curved section is adjacent to the outlet section and has a concave curvature. The movable diffuser hub is configured to move with respect to a central flow axis relative to the diffuser wall and can thereby alter a fluid flow through the radial diffuser.

A flow metering system includes a pump configured to urge a fluid flow from a fluid source, and a recirculation line located at the pump. A pressure regulating valve is located along the recirculating line. One or more fluid delivery lines extend downstream of the pump to deliver the fluid flow to one or more fluid consumers. A flow control valve is located along each fluid delivery line of the one or more fluid delivery lines. A system controller is operably connected to the pressure regulating valve and the one or more flow control valves. The system controller is configured to maintain a selected delta pressure and a selected flow rate of the fluid flow by operation of the pressure regulating valve and the one or more flow control valves.
