ABSTRACT:
A device having a first flow meter (2) and a second flow meter (3). The first and the second flow meters work according to a Coriolis principle. The first flow meter includes a first measuring tube (7). The second flow meter includes a second measuring tube (10). The first flow meter and the second flow meter are disposed in a common housing (4,5,6). The first flow meter and the second flow meters have different eigenfrequencies because of a first vibration-influencing device (18) attached to the first flow meter and a second vibration-influencing device (19) attached to the second flow meter.
