An apparatus and a process for quickly and accurately determining in-line the rheology of molten polymer streams, said apparatus comprising a cam means and a pressure wall means, one of which is a rotating member and the other one is a stationary member, the rotating member dragging molten polymer into a wedge-shaped clearance between the cam means and the pressure wall means, polymer pressure within the clearance being sensed by a pressure detection device capable of producing a signal responsive to said pressure in the form of a display, a graph, or an arbitrary numerical value, but preferably being transmited to a computer programmed to calculate apparent melt viscosity of the polymer by the application of the Reynold's theory of lubrication.
