Measuring assembly designed for monitoring the bunkering of a large ship with a liquid product of the mineral oil or petrochemical industry, comprising at least two parallel pipe lines arranged in the course of a bunker line leading into a bunker tank of the ship for dividing the inflowing and collecting the outflowing liquid product , - wherein a Coriolis mass flow meter , a pressure gauge and a control valve having an actuating drive and a position controller are arranged in each of the pipe lines one after the other in the flow direction and - wherein the Coriolis mass flow meters , pressure gauges and control valves are connected to a control and evaluation device , which is embodied - to determine from the measured values delivered by the Coriolis mass flow meters the mass flow and relevant measured values of the liquid product derived therefrom and - during the bunkering, to set the control valves individually by controlling the associated position controllers as a function of the measured values delivered by the Coriolis mass flow meters and the pressure gauges in a manner such that - the measured flow in only one of the parallel pipe lines is greater than zero and less than a predetermined threshold value and in the remaining pipelines (4, 55 is either zero or reaches the flow threshold value and - in such cases the measured pressure does not fall below a predetermined pressure threshold value. - wherein a Coriolis mass flow meter , a pressure gauge and a control valve having an actuating drive and a position controller are arranged in each of the pipe lines one after the other in the flow direction and - wherein the Coriolis mass flow meters , pressure gauges and control valves are connected to a control and evaluation device , which is embodied - to determine from the measured values delivered by the Coriolis mass flow meters the mass flow and relevant measured values of the liquid product derived therefrom and - during the bunkering, to set the control valves individually by controlling the associated position controllers as a function of the measured values delivered by the Coriolis mass flow meters and the pressure gauges in a manner such that - the measured flow in only one of the parallel pipe lines is greater than zero and less than a predetermined threshold value and in the remaining pipelines (4, 55 is either zero or reaches the flow threshold value and - in such cases the measured pressure does not fall below a predetermined pressure threshold value. - to determine from the measured values delivered by the Coriolis mass flow meters the mass flow and relevant measured values of the liquid product derived therefrom and - during the bunkering, to set the control valves individually by controlling the associated position controllers as a function of the measured values delivered by the Coriolis mass flow meters and the pressure gauges in a manner such that - the measured flow in only one of the parallel pipe lines is greater than zero and less than a predetermined threshold value and in the remaining pipelines (4, 55 is either zero or reaches the flow threshold value and - in such cases the measured pressure does not fall below a predetermined pressure threshold value. - the measured flow in only one of the parallel pipe lines is greater than zero and less than a predetermined threshold value and in the remaining pipelines (4, 55 is either zero or reaches the flow threshold value and - in such cases the measured pressure does not fall below a predetermined pressure threshold value. <EOS>
