Abstract:
1. An apparatus for measuring a mass flow with a driven measuring wheel carried by a shaft, and impinged upon axially by the mass flow, wherein the shaft also bears a driving spur wheel which meshes with an intermediate spur wheel, wherein the intermediate spur wheel is held in its position by a force-measuring device and meshes with a operative spur wheel which is driven by a drive motor, wherein the diameter of the driving spur wheel is greater than 0.3 times the diameter of the measuring wheel, characterized in that: (a) a leverage supported axially parallel to the shaft of the intermediate spur wheel for the force-measuring device in order to transmit the measuring force; (b) at least the driving spur wheel of the shaft and the intermediate spur wheel are arranged on a crossbeam which protrudes into the mass flow in the gear housing; (c) the housing of the apparatus has a low overall height which is small than or equal to twice the diameter of the measuring wheel and (d) the inlet opening for the material and the cutlet opening of the mass flow in the housing are arranged directly one below the other in alignment.
