Device for measuring the flow of urine from a patient with a measuring cup (11) having an opening for urine flow and is arranged, with respect to a transducer measurement values (4), so that can be detected a displacement (dZ) of the measuring cup (11) relative to the transducer measured values (4) as a measure of the volume of urine accumulated in the measuring cup (11), thereby causing the displacement (dZ) for increasing the total weight the measuring cup (11) corresponding to the weight of the urine accumulated in the measuring cup (11) during the flow of urine through the measuring cup (11), characterized in that in the measuring cup (11) is mounted an annular magnet or multiple magnets (16) with the same polarization direction, the transducer measured values (4) is mounted one second annular magnet or multiple second magnets (12) with the same polarization direction, the magnetic poles magnet ring or multiple magnets (16) are arranged with respect to the magnetic poles of the second annular magnet or multiple second magnets (12) for generating a magnetic force of repulsion or attraction between the measuring cup (11) and the transducer measured value (4), the position of the measuring cup (11) relative to the transducer measured values (4) for compensating the magnetic force by the total weight acting on the measuring cup being defined (4 ) and opposes the magnetic force.Dispositivo para medir el flujo urinario de un paciente con un vaso de medición (11) que presenta una abertura para la salida de orina y que está dispuesto, con respecto a un transductor de valores de medición (4), de modo que puede detectarse un desplazamiento (dZ) del vaso de medición (11) con respecto al transductor de valores de medición (4) como medida del volumen de orina acumulada en el vaso de medición (11), provocándose el desplazamiento (dZ) por un aumento del peso total del vaso de medición (11) que corresponde al peso de la orina acumulada en el vaso de medición (11) durant
