Abstract
Relations between attenuation and phase shift of electromagnetic waves passing through a wet substance and weights of water and dry substance have been used for calculation of the real value of moisture content of the substance. The result appears to be independent of the denity of the substance, its layer thickness and flatness of its surface. Measuring set-up for continuous measurement requires some extensions when compared with a single-parameter measuring set-up, but it is still supplied by a oscillator working at one constant frequency and it consists of only one sensor.Keywords
