Abstract
An apparatus for measuring the water content of a water-containing liquid mixture contained in a tight chemistry tank includes a heating device for controlling the temperature of the liquid mixture to a temperature near the boiling point of the liquid mixture, a cooling medium system disposed at the top of the tight chemistry tank having a cooling medium inlet and a cooling medium outlet, a temperature measurement system for determining the temperature difference between the cooling medium inlet and outlet, and a computing device for calculating the water content of the liquid mixture from the temperature difference. Also provided is a tank for supplying water to the liquid mixture, and a control system for adjusting the amount of water supplied from the tank based upon the water content measured by the measuring apparatus. Also provided is a method for measure the water content.
