  • Publication number: 20210254623
    Abstract: A pumping device includes a single-use device and a reusable device. The single-use device is to be inserted into the reusable device and includes two pump units in series, one behind the other. Each pump unit includes a rotor for a bearingless motor, and can be magnetically levitated and driven without contact for rotation about an axial direction. The reusable device includes a stator for each rotor which form an electromagnetic rotary drive for rotating the rotor about the axial direction. Each stator is a bearing and drive stator with which the rotor can be magnetically driven and levitated without contact with respect to the stator. An independent control device is provided for each stator, and can independently activate a respective stator.

  • Patent number: 11047721
    Abstract: 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.
