In this paper, ways of moisture meters enhancement are considered, with the purpose to use them in cereal-processing technologies. The paper suggests a new design concept of moisture meter for measuring grain moisture. Multiparameter measurement is the main principle of the given moisture meter. Capacitance method with correction for bulk grain weight and temperature is basic.
