ABSTRACT:
The rheometer is located in a non-return branch of a molten polymer line and includes, in succession, a fixed-speed pump, a first capillary tube, and a second capillary tube in series with the first tube. The second tube has a diameter less than or equal to that of the first tube, and emerges into a fluid medium at regulated pressure. Pressure-sensors at the inlet of each tube determine the pressure loss between the inlet of each tube and the fluid medium at regulated pressure. The temperature is monitored by means that are at least party external to the body of the rheometer.
