Abstract
For measuring the water content of a web in the wire section of a paper machine, at least one radiofrequency-operated resonator sensor forms an electric near field, in which a web affects the resonance frequency of each resonator sensor. The water content of the web is measured as a function of the resonance frequency of each resonator sensor in a measuring unit.
