    ANALYSIS OF MEASURED PUMP PARAMETERS.
    Information about operating modes of a pumping system and values of required flows and heads and also their fluctuations in time can be presented in the graph.
    Pump's operating points

    Example of data collected during tests made on the pumping station of a water supply system.

    This data represents the cloud of operating modes during the defined period of time.

    Are throttle and bypass control used in the pumping system?
    How characteristics of installed pumps provide all required points?
