Inline Rheometer Specifications

System Specifications

Display Spectra (image), velocity profile, viscosity at multiple quality control set-points, shear stress vs shear rate plots
Main Outputs Spectra (image), velocity profile, rheology/viscosity at multiple quality control set-points, shear stress vs shear rate, flow rate, acoustic parameters
Viscosity* +/- 5% or better
Measurement Rate 10 – 60 s per measurement (for Rheology/Viscosity, flow measurements are faster)
Flow Velocity Range** 0.1 – 7 m/s
Reynolds Number 0.1 – 2000 (Laminar flow required for rheology)
Viscosity Range*** 40 mPa.s – 70 Pa.s
* The accuracy of viscosity is dependent upon process conditions and the measured fluid and also on the reference method used
** Flow velocity range is dependent upon pipe diameter and application
*** Viscosity range is dependent upon differential pressure sensor used and measured fluid
