A Coriolis-type mass flow sensor (1) is disclosed which is as insusceptible to external disturbances as possible and which can be installed in a conduit and, during operation, is traversed by a fluid to be measured. The conduit is connected via a fluid inlet (113) and a fluid outlet (114) with a casing (11) in which a rigid support base (12) is disposed. The support base (12) is connected with the casing via at least one mechanical damping element (13, 14, 20). A measuring tube (15) traversed by the fluid ends in the fluid inlet and the fluid outlet. A portion (151) of the measuring tube which is to be set into vibration is attached to the support base by an inlet-side fixing means (121) and an outlet-side fixing means (122). An inlet-side connecting portion (152) of the measuring tube extends from the inlet-side fixing means (121) to the fluid inlet (113), and an outlet-side connecting portion (153) extends from the outlet-side fixing means (122) to the fluid outlet (114). A vibrator assembly (16) for vibrating the tube portion (151) acts between the casing (11) and the support base (12). Two vibration sensing elements (17, 18) mounted partly on the tube portion (151) are disposed near the inlet-side fixing means (121) and near the outlet-side fixing means (122), respectively.
