In-Line Rheometer

RheoStream is a rheometer for real time in-process measurement of viscosity, shear thinning and apparent yield stress in viscous non-Newtonian liquids.

                                        ● Inline viscometers providing real-time data on viscosity

                                        ● Manual in-plant rheometers providing empirical rheology values

                                        ● Laboratory rheometers providing a full set of rheology data


The measures provided by RheoStream®

RheoStream measures viscosity, shear-thinning, and apparent yield stress in non-Newtonian liquids.

The output data from RheoStream :

                                        ● Reports viscosity (or shear stress) at 3 pre-selected shear rates

                                        ● Optionally, calculates and report alternative viscosity model parameters (Bingham, Herschel-Bulkley, Cassons)

                                        ● Displays the temperature at which the measurement takes place.


Customized Liquid Measurement with RheoStream®

RheoStream works for liquids with particles smaller than 200µm(Max. 500μm). The sample coming in may be 10-60°C, and is cooled/heated to the desired measuring temperature. RheoStream covers a shear rate range of 1.5-1000 [1/s]. The viscosity range depends on the shear rate of the measurement

“Application area” indicated in the picture below :

                                        ● Above the upper solid red line, the samples are too thick, limited by the internal parts

                                        ● Below the lower red line, the samples are too thin, reaching the signal/noise limit of the instruments


How RheoStream® Works

                                        ① A sample is drawn from process equipment

                                        ② The syringe pump controls flow rates in pulses ③

                                        ④ A preheater/cooler ensures a steady temperature of the measurement

                                        ⑤ The liquid flows through a thin tube (capillary)

                                        ⑥ A pressure difference (ΔP) is measured for each pulse

                                        ⑦ The instrument computer converts pressure signals into viscosity values

                                        ⑧ Displays results on the user interface

                                        ⑨ Spent sample is collected as waste
