ABSTRACT:
A device for determining the material parameters, in particular the water content, of a substance in a dielectric medium conducted through a pipeline, the device including a waveguide of a microwave system at least partially enclosing the pipeline. Transmission or reflection of microwave radiation in the waveguide is evaluated continuously or in cycles. Continuous measurement of such media, in particular liquid media, can be effected and in particular can be made automatically without requiring steps for sample taking and performance of the measuring process per se.
