ABSTRACT:
An assembly for use in a rotary positive displacement fluid meter having an inner body wall surface that includes a first impeller having an outer surface located within the rotary positive displacement fluid meter and adapted to be directly driven by a fluid flow. The assembly also includes a flexible edge member situated at a distal end of the impeller such that there is a clearance between the flexible edge member and the inner body wall of the rotary positive displacement fluid meter. The impeller defines a longitudinal axis and the flexible edge member has a length along the longitudinal axis and a width in a direction that is orthogonal to the longitudinal axis.
