Abstract:

A method for preparing a liquid flow having pre-defined characteristics by mixing liquid flows of at least two different component stock solutions with each other comprises the steps of determining a selected property value for one or more of the stock solutions by sensing, in a flow of each stock solution separately, at least one characteristic related to the property value for the stock solution, and based on the determined property value or values, mixing the stock solution flows in mixing ratios giving the desired mixed liquid flow. A system for carrying out the method comprises sensor means and a control unit, wherein the control unit is arranged to evaluate the characteristics sensed by the sensor means and provide relative ratios of stock solutions required to obtain a mixed liquid flow having the pre-defined characteristics.
