Abstract: A volumetric flow measuring and metering device for flowable solids as a flow passage through which a flow of bulk material may be passed. An obturating device is positioned at the bottom end of the flow passage and is movable in a linear direction toward and away from the bottom end. The obturating device is positioned relative to the bottom end of the flow passage at a distance that imparts a consolidated, column-like flow of the bulk material in the flow passage. A speed sensor operates to measure a speed of consolidated, column-like flow of the bulk material in the flow passage. A controller uses the speed data from the speed sensor to calculate a volumetric flow rate of the bulk material flowing through the flow passage. The obturating device can be selectively positioned to increase or decrease the volumetric flow rate of the bulk material. Other aspects are also provided.
