摘要： A mixing device for mixing at least two substances includes a single-use device and a reusable device. The single-use device includes an impeller, vanes, and a cup for receiving the rotor housing. A magnetically effective core is in the rotor housing. The reusable device includes a stator to contactlessly magnetically drive the impeller about the axis of rotation and magnetically levitate the impeller with respect to the stator. A plurality of stabilizing elements is on the impeller for stabilizing the impeller against tilting. Each stabilizing element is arranged between two vanes and extends from a radial inner edge to a radial outer edge with respect to the radial direction, and each radial outer edge has a distance from the axis of rotation which is smaller than half the outer diameter of the impeller.

摘要： An ultrasonic measuring device for measuring a fluid flowing in a pipe includes a housing and transducers. The housing receives and fixes the pipe, so that the fluid can flow through a central recess in a flow direction. The ultrasonic transducers emit and receive ultrasonic signals. Two first ultrasonic transducers are arranged laterally on a first side of the central recess, and two second ultrasonic transducers are arranged on a second side of the central recess. The second side is opposed to the first side, so that the recess is located between the first and the second ultrasonic transducers, and the ultrasonic transducers are arranged and aligned so that one of the first ultrasonic transducers emits a first measuring signal to one of the second ultrasonic transducers obliquely to the flow direction and receive a second measuring signal emitted by the second ultrasonic transducer obliquely to the flow direction.

摘要： An electromagnetic rotary drive includes a single-use device for single use and a reusable device for multiple use. The single-use device includes a rotor housing with a rotor, a connecting tube for a fluid, and a single-use component. The rotor housing has an inlet and an outlet, and the rotor is provided in the rotor housing for rotation about a desired axis of rotation defining an axial direction. The rotor can be magnetically driven without contact, and the connecting tube connects the inlet or the outlet of the rotor housing to the single-use component such that in the operating state the fluid flows through the connecting tube. The reusable device includes a stator, by which the rotor is magnetically driven without contact for rotation about the desired axis of rotation in the operating state.

The filter unit is in the filter housing and completely enclosed by the filter housing. The filter unit has a filter element delimiting a fluid space from a filtrate space, filtrate is discharged from the filtrate space through the first outlet. The filter unit includes a magnetically effective core in a disk-shaped or ring-shaped manner. The drive device has a drive housing in which a stator is disposed to drive the rotation of the filter unit. The stator is a bearing and drive stator which interacts with the magnetically effective core as an electromagnetic rotary drive, so that the filter unit is capable of being magnetically driven without contact and magnetically levitated with respect to the stator.
