METHOD FOR DETERMINING A CHEMICAL INTAKE CAPACITY OF A PROCESS MEDIUM IN A MEASURING POINT AND MEASURING POINT FOR DETERMINING A CHEMICAL INTAKE CAPACITY OF A PROCESS MEDIUM

A method for determining a chemical intake capacity of a process medium includes steps of providing a measuring point and an analytical measuring device, closing an outlet valve to the drain so that no process medium is discharged and closing the inlet valve so that no additional process medium is fed from the first inlet. The method includes circulating the analyte and process medium through the pump so the mixture flows into the analytical measuring device at a predetermined flow velocity. Further, the method includes detecting a measured value using the analytical measuring device until the measured value exceeds a limit value. The predetermined volumes are summed to form a total volume of the analyte, and a chemical intake capacity of the predetermined medium is determined based on the total volume of the analyte fed in.
