Abstract
The present invention relates to a method and an apparatus for measuring a mass flow of flowable bulk materials according to the Coriolis principle of measurement. The apparatus comprises a vane wheel by which a mass flow that is supplied in axial direction can be radially redirected and by which it is possible to detect the drive torque that that necessary to achieve the redirection. A drive shaft that is routed through the top side of the housing is configured as a hollow shaft through which the bulk material can be fed to the vane wheel in vertical direction toward the center of its axis of rotation.
