A method for the gravimetric mass metering of bulk solids via a container with the bulk solid to be metered and a volumetric conveying device, via which the bulk solid coming from the container with a mass flow, which chronologically follows a target value for a target feed rate, is conveyed, and a differential metering scale suitable for such purpose. The bulk solid, after leaving the conveying device can pass through a mass flow measuring device and the mass flow measuring device calculates a second signal representing the mass flow, and based on the second signal representing the mass flow and the first control signal, a second control device calculates a second signal and delivers the signal to a drive of the conveying device for controlling the conveying device.
