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 (4, 5) 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 (41, 51), a pressure gauge (42, 52) and a control valve (43, 53) having an actuating drive (44, 54) and a position controller (45, 55) are arranged in each of the pipe lines (4, 5) one after the other in the flow direction and - wherein the Coriolis mass flow meters (41, 51), pressure gauges (42, 52) and control valves (43, 53) are connected to a control and evaluation device, which is embodied - to determine from the measured values delivered by the Coriolis mass flow meters (41, 51) the mass flow and relevant measured values of the liquid product derived therefrom and - during the bunkering, to set the control valves (43, 53) individually by controlling the associated position controllers (45, 55) as a function of the measured values delivered by the Coriolis mass flow meters (41, 51) and the pressure gauges (42, 52) in a manner such that - the measured flow in only one of the parallel pipe lines (4, 5) 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 (41, 51), a pressure gauge (42, 52) and a control valve (43, 53) having an actuating drive (44, 54) and a position controller (45, 55) are arranged in each of the pipe lines (4, 5) one after the other in the flow direction and - wherein the Coriolis mass flow meters (41, 51), pressure gauges (42, 52) and control valves (43, 53) are connected to a control and evaluation device, which is embodied - to determine from the measured values delivered by the Coriolis mass flow meters (41, 51) the mass flow and relevant measured values of the liquid product derived therefrom and - during the bunkering, to set the control valves (43, 53) individually by controlling the associated position controllers (45, 55) as a function of the measured values delivered by the Coriolis mass flow meters (41, 51) and the pressure gauges (42, 52) in a manner such that - the measured flow in only one of the parallel pipe lines (4, 5) 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 (41, 51) the mass flow and relevant measured values of the liquid product derived therefrom and - during the bunkering, to set the control valves (43, 53) individually by controlling the associated position controllers (45, 55) as a function of the measured values delivered by the Coriolis mass flow meters (41, 51) and the pressure gauges (42, 52) in a manner such that - the measured flow in only one of the parallel pipe lines (4, 5) 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 (4, 5) 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.
