A rheometer for determining and/or monitoring the flow behavior of viscous fluids, in particular plastic melts and plastic solutions, having a housing in which at least one substantially rectilinear channel is formed between an inlet opening and an outlet opening, wherein the channel has a rectangular cross section, and having multiple pressure measurement devices which are arranged along the channel, wherein the channel is provided over its length with a cyclically narrowing and widening cross section, wherein two channels which are parallel to one another and which are separated from one another by means of at least one web are formed, wherein the web forms, together with a housing wall, a gap, and wherein, in relation to a respective channel length, the narrowing and widening cross sections of parallel channels are different from one another.
