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
