Abstract:
1. A method of measuring two or more parameters of a composition, which includes water, that comprises the steps of: a. directing microwave radiation over a spectrum of wavelengths from an antenna to be incident upon the composition; b. measuring the microwave radiation over the spectrum of wavelengths that emerges from the composition; c. determining a reflected and/or transmitted transfer function of the composition over the spectrum of wavelengths; d. relating the determined transfer function of the composition over the spectrum of wavelengths to two or more parameters of the composition, that include water temperature and at least one of composition percent moisture or composition basis weight, by applying a model, with the proviso that an independent temperature measurement of the composition is not required; and e. predicting the water temperature and at least one of composition percent moisture or composition basis weight.
