Method and apparatus for measuring the amount of ice in an aqueous ice slurry

摘要

The ice content of a mixture of ice and liquid water is determined by (a) measuring the electrical conductivity Ci of the original water at a temperature above its freezing point and before any of it has been converted to ice; (b) cooling the water to produce a mixture of ice and a liquid water phase; (c) measuring the electrical conductivity Cn of the liquid water phase; and (d) computing the fraction of ice in the mixture by use of the equation F=1-Ci/Cn wherein F is the fraction of ice in the mixture, Ci is the electrical conductivity of the original water before ice formation therein, and Cn is the electrical conductivity of the liquid water phase in the mixture having the ice fraction F.
