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.

An antenna arrangement for coupling high frequency electromagnetic waves into or out of a pipe-shaped hollow body includes two patch antenna elements that are located opposite one another and integrated in the pipe inner wall () of the hollow body (), and have curved surfaces fitted to the curved longitudinal pipe inner wall of the hollow body (). An apparatus for mass flow measurement includes at least two of such antenna arrangements axially spaced apart from one another in a conveyor pipe section.
