    Abstract: A method and a control arrangement are disclosed to measure a total flow rate through a pump device before a pump pressure or rotational speed change; and to change at least one of: the pump pressure by a predetermined pressure step or the pump rotational speed by a predetermined rotational speed step. The arrangement can measure a total flow rate through the pump device after the pump pressure or rotational speed change; and determine a need for a further pump pressure or rotational speed change step based on total flow rate measurements carried out before and after the pump pressure change.

    Abstract: A method is provided for detecting the correct rotational direction of a centrifugal apparatus. The method includes rotating the centrifugal apparatus in a first direction, acquiring first frequency data relating to the step of rotating the centrifugal apparatus in the first direction, rotating the centrifugal apparatus in a second direction, which is opposite to the first direction, and acquiring second frequency data relating to the step of rotating the centrifugal apparatus in the second direction. The method also includes detecting the correct rotational direction of the centrifugal apparatus based on comparing the first frequency data with the second frequency data, the comparison being carried out with respect to at least one significant frequency range. In each of the at least one significant frequency range, a smaller magnitude is interpreted as an indication of the correct rotational direction.
