A method for detecting deposits in a pipe system of an apparatus is proposed, the apparatus being flowed through by a fluid. In the method it is provided that at least one microwave probe is introduced into the pipe system in such a way that the fluid flows against a window () of the microwave probe that is transparent to microwave radiation, and that microwaves are coupled into the pipe system by way of at least one microwave probe, wherein a reflection measurement is carried out with one or two microwave probes, and/or at least two microwave probes are introduced into the pipe system at a distance from one another and a transmission measurement is carried out, wherein a comparison of measurement data with a reference or a previous measurement is used to deduce a constriction in the pipe system segment and the free cross-section at the constriction is determined, the detection of a constriction being used to deduce the presence of deposits. Further aspects of the invention relate to a microwave probe for coupling microwave radiation into the pipe system of an apparatus and to a measuring device for carrying out the method that comprises at least one such microwave probe.
