PCT No. PCT/EP95/04786 Sec. 371 Date Jun. 5, 1997 Sec. 102(e) Date Jun. 5, 1997 PCT Filed Dec. 5, 1995 PCT Pub. No. WO96/18088 PCT Pub. Date Jun. 13, 1996In order to improve the metering accuracy, especially with a strongly fluctuating feed material supply, a method and an apparatus for continuous, gravimetric metering and mass flow determination of flowable materials are proposed, wherein the output of the metering device (8) is regulated with a time offset to match the set-point flow rate in dependence on the instantaneous mass flow determined at the flowmeter (4).
