ABSTRACT:
A system and a method for controlling the concentration of dissolved matter in a liquid in a boiler or still, wherein a first sensor measures the electrical conductivity of the incoming liquid and a second sensor measures the electrical conductivity of the liquid in the boiler or still. The measured conductivities are then compared and a signal is generated which represents the relation of the conductivities. This signal is, in turn, compared with a preset value and the difference is used to control the flow of incoming liquid which serves to dilute the liquid in the boiler.
