Zusammenfassung:PCT No. PCT/AU91/00096 Sec. 371 Date Sep. 15, 1992 Sec. 102(e) Date Sep. 15, 1992 PCT Filed Aug. 18, 1991 PCT Pub. No. WO91/14167 PCT Pub. Date Sep. 19, 1991.A rheometer or viscometer for continuously measuring the rheological properties of non-Newtonian, mixed phase fluids or slurries. The device has a vertically disposed, inverted U-tube to maintain solids in suspension and, therefore, exhibit a homogeneous character. The fluid flow rate is controlled to assure nonturbulent laminar flow through the tube. Pressure is measured at as point in each leg of the U-tube and compared. For a constant flow rate, the pressure drop over the tube is used to measure the viscosity of the fluid in the tube.
