ABSTRACT:
A mass through-flow is continuously measured by measuring the Coriolis forces that are caused by the mass flow passing through a winged wheel. The mass flow is introduced centrally onto the winged wheel which rotates with a constant r.p.m. and diverts the mass flow radially outwardly. The Coriolis forces and thus the corresponding reaction torques which are proportional to the mass through-flow are measured with the aid of a torque joint interposed between a housing of the winged wheel and a drive motor for the shaft that drives the wheel. Force sensor elements, preferably in the form of bending beams, are incorporated into the torque joint and are deflected by the reaction torque moment applied to the motor housing. These bending beams provide an output signal that is proportional to the mass through-flow through the apparatus.
