INLINE RHEOLOGY/VISCOSITY, DENSITY, AND FLOW RATE MEASUREMENT

摘要

A system of performing inline measurements of flow rate, density, and rheology of a flowing fluid. The system includes a rheology measurement subsystem, a density measurement subsystem, and a pressure sensor for measuring the pressure of the test fluid within the vertical tube at a location y2 downstream from y1 and displaced vertically from y1 by a distance Δh.

1. A system for performing inline measurements of flow rate, density, and rheology of a flowing fluid, wherein said system comprises:
a rheology measurement subsystem (100), said rheology measurement subsystem comprising:
a horizontal tube (110) of internal radius rH having an upstream end and a downstream end;a velocity profile measurement device (130) configured to measure a velocity profile of a test fluid flowing through said horizontal tube at a distance x0 from said upstream end; and,wall shear stress determining means for determining wall shear stress at a boundary between said flowing fluid and an inner surface of said horizontal tube (110); a density measurement subsystem (200), said density measurement subsystem comprising:
a vertical tube (210) of internal radius rV in fluid connection with said horizontal tube;a first pressure sensor (220) configured to measure pressure of said test fluid within said vertical tube at a location y1; and,a second pressure sensor (230) configured to measure pressure of said test fluid within said vertical tube at a location y2 downstream from y1 and displaced vertically from y1 by a distance Δh.
