  • Rheometer
    Patent number: 10948393
    Abstract: A rheometer for determining and/or monitoring the flow behavior of viscous fluids, in particular plastic melts and plastic solutions, includes a housing, in which at least one substantially rectilinear channel is formed between an inlet opening and an outlet opening, the channel having a rectangular cross section, and a plurality of pressure measuring devices which are arranged along the channel, wherein the channel is provided over its length with a cyclically narrowing and widening cross section.
    Type: Grant
