It is important to find a method using the dielectric properties of the material to determine moisture content independent of the density in developing microwave moisture meter. Moisture measurement based on the dielectric properties of the material can be applied in various microwave techniques. In this paper, a new method using dielectric constants only for density-independent moisture determination is proposed. The new method was used to measure moisture content of green tea, and the results are presented. It was shown that the Root Mean Square Error (RMSE) is 2.4% in the moisture measurement for the samples in 8-49% moisture range and 0.14-0.69 g/cm3 density range. The comparison of the proposed method with the former method on green tea was also presented. The results show that the accuracy of moisture determination by the proposed method is better than the former method.
