Patent ID: 6952951

Claim:
A method for measuring a viscosity of a liquid as a function of a temperature of the liquid, the method comprising: providing a viscosity sensor at a first location of the liquid; providing at least one temperature sensor at a second, different location of the liquid; performing at least one of the following: (a) reaching a conclusion on the temperature of the liquid at the first location of the viscosity sensor at a specified point in time, and (b) reaching a conclusion on the viscosity of the liquid at the second location of the temperature sensor at a specified point in time; and discarding a measured value of at least one of the viscosity sensor and the temperature sensor if a measure of an inhomogeneity of the temperature of the liquid exceeds a specified threshold, wherein the at least one of (a) and (b) is performed starting from at least one of the following: (1) at least one of temperature measurements and viscosity measurements made in the past, and (2) a plurality of temperature measurements at different locations at the specified point in time.
