Patent ID: 6996479

Claim:
An apparatus for measuring the water content of a water-containing liquid mixture contained in a tank, the water-containing liquid mixture having a boiling point, the apparatus comprising: a tank for holding the water-containing liquid mixture, said tank having a top; a heating device for controlling temperature of the liquid mixture to a temperature near the boiling point of the liquid mixture; a cooling medium system for cooling the liquid mixture, said cooling medium system having: a condensing surface to condense water evaporating from the liquid mixture in said tank; and a cooling medium inlet and a cooling medium outlet, said cooling medium system being disposed at said top of said tank and conveying a cooling medium; a temperature measurement system connected to said cooling medium system for determining a temperature difference between said cooling medium inlet and said cooling medium outlet; and a computing device connected to said temperature measurement system for calculating the water content of the liquid mixture from said temperature difference.
