Abstract
High accuracy mixing of fluids in a disposable fluid processing system with at least two pumps is provided by a method where a calibration fluid volume is pumped through each pump via a flow meter at at least one calibration pump speed while registering the flow rate using data output from the flow meter, a pump calibration function is calculated from the calibration pump speed and flow rate data and two or more operation fluids are mixed to a predetermined mixture ratio and predetermined flow rate by controlling the pump speed of the respective pumps in accordance with the pump calibration functions.
