Abstract:
    The present invention relates to a turbine flowmeter includes an impeller wheel mounted, so that it can rotate, between an upstream hub and downstream hub in a tubular element. The hubs are mounted securely in the tubular element by ribs. A device for regulating to compensate measuring errors resulting from manufacturing tolerances is provided at least on the upstream hub. To provide the regulating effect as well as to avoid an asymmetric flow against the impeller wheel the regulating device includes a pivotable regulating part 6 including fins 9 and is located immediately downstream of the upstream hub 1 and a drive device for pivoting the rotatable. Fins 9 will be located in a turbulence region immediately downstream of the ribs 4 when regulating part 6 is off operative position, and fins 9 will be projected into the flow cross-section when regulating part 6 is in the operative position.
