1. An apparatus for generating a fluid flow, said apparatus comprising:

  • a displacement pump with at least one flow vessel of deformable lumen, which serves to conduct a fluid, with a pump drive for producing displacement motions of the flow vessel which deform the lumen and cause the fluid flow, and with a support means for holding the flow vessel; and

    a measuring arrangement responsive to the displacement motions performed by the flow vessel, with a pressure sensor sensing a static pressure in the fluid and providing a sensor signal representative of the displacement motions, and with evaluation electronics for the sensor signal.
