ABSTRACT:
A flow meter includes a flow channel having walls and defining a direction of flow. Stators are provided, having walls, disposed at least partially within the flow channel. A rotor is included for rotating with respect to the stator. A one piece retainer is provided for assisting in limiting axial rotor movement comprising a first pair of spaced apart wall portions for engaging the flow channel walls wherein each wall portion in the first pair of wall portions is located on a side of an axis opposite from the other. A second wall portion is located on the axis for engaging the stator wall wherein compression of each of the first pair of wall portions toward the axis results in a component of force being applied to the second wall portion along the axis.
