Abstract
A device for the measurement of the mass flow, in particular, of a bulk material flow, by the Coriolis measuring principle, comprising a motor with an impeller, driven at constant speed. The bulk material flow is dispensed onto the impeller, radially deflected and measured by means of a force measurement device for the drive torque of the impeller. A drive shaft supporting the impeller is rotatably mounted in a bearing sleeve and is coaxially enclosed by the same. The bearing sleeve is driven at a speed which corresponds to the speed of the drive shaft. The force measurement device is arranged directly between the drive shaft and the bearing sleeve.
