WebIn many cases the flow curve is the first and usually also the most important rheological measurement. It shows the flow behaviour for low shear rates (slow motions) as well as high shear rates (fast motion). Low … WebICAR Rheometer 73 recommended. During each step the speed is held constant and the average speed and torque are recorded. The plot of torque versus speed of vane rotation is the flow curve. The ICAR Rheometer software performs all the necessary functions: operates the driver, records the torque, computes test results, and stores data.
