Mixer sensors and methods for using same

摘要

Apparatuses for measuring rheological properties of fluids and methods for using same are provided. In a general embodiment, the present disclosure provides a mixer sensor that is configured to be attached to a rheometer drive head and used to measure rheological properties of a fluid having particulates over a wide range of temperatures and shear rates. Apparatuses capable of obtaining rheological data of a fluid having particulates over a wide range of temperatures and shear rates provides for more precise rheological measurements. The temperatures may be very high temperatures that exceed 100° C., and the shear rates may includes a range of shear rates that are typically found in a processing pipeline system.

主权项

1. An apparatus for measuring rheological properties of a material, the apparatus comprising:
a drive head attachment so constructed and arranged to attach to one of a rheometer and a viscometer; a shaft comprising at least three blades, wherein the plurality of blades are radially spaced about an axis of the shaft, wherein the drive head attachment is configured to receive a top end of the shaft therein, wherein each of the plurality of blades is rotated about 20° to about 80° from horizontal, and wherein the plurality of blades are vertically spaced from each other by about 0.25 inches to about 1.25 inches; and a base configured to receive an end of the shaft, and wherein the base further comprising at least one o-ring groove configured to accept an o-ring seal and wherein the base is configured to receive a bottom end of the shaft.
