Abstract: There is disclosed an axial flow turbine-type flow meter in which a rotor having helical blades is supported to rotate on a shaft disposed axially of a conduit having a cross section graduated along the length thereof. This shaft in turn is supported from the walls of the conduit on elastic flexible members which yield under the stress of a flow of fluid through the conduit so that the rotor shifts axially of the conduit through small distances in accordance with the rate of flow of fluid. In order to vary the amount of this shift produced by given rates of flow, means are provided to vary the effective length of at least one of these flexible members.
