Abstract
A pair of multi-frequency ultrasound transducer surround a fluid flow and are configured to operate under computer control in both a mono-static and a bi-static mode at each of the multiple frequencies. In the mono-static mode, pulsed wideband Doppler shift measurements provide the velocity profile across the fluid flow which can be combined with measured pressure drops to determine the rheogram—a plot of shear stress versus shear rate. Velocity profile data from each frequency can be combined to form a composite velocity profile. In the bi-static mode, transmission data is collected that improves the accuracy and robustness of the velocity profile and provides supplemental material property information. The system is configured for automated operation for a wide variety of fluid types and can be reconfigured and/or monitored remotely.
