Abstract

A crystallisation solution supersaturation (Ts) measurement procedure measures the temperature by cooling and heating a limited volume of fluid and detecting crystallisation to obtain results for two different temperature change rates controlled using Peltier elements different thermal impedances with multivariable processing to calibrate the high rates from the low. Independent claims are included for sensor systems using the procedure.
