Abstract

The performance of a newly developed fully digital UVP-PD (Ultrasonic Velocity Profiling with Pressure Drop) electronics is tested and validated with a Non-Newtonian model solution. For this purpose, a piston setup is used to create well defined flow conditions to enable a comparison of theoretical and measured velocity profile. The rheometric parameters are estimated in-line with UVP-PD by using three different approaches and compared with those obtained from off-line rotational rheometer. Considering the shear rate range available in the pipe flow, a good agreement of in- and off-line results is found.
