1. A fluid flow meter, comprising:

  • a turbine having a hub for mounting on a supporting structure affixed to the interior of a housing having inlet and outlet ends, for both rotational and downstream movement of said turbine with respect to said supporting structure, in response to the rate of flow of fluid through said housing;

    means for biasing said turbine with forces in directions opposite to those applied to said turbine by said fluid flow; and

    means for determining the combined rotational and downstream displacement of said turbine, whereby said flow rate can be translated to more than 360°

    of angular displacement of said turbine.
