Patent number: 10451532Abstract: A portable viscometer includes a pump mechanism which cooperates with a positive displacement sample container referred to as a positive displacement pipette, for dispensing, at a known flow rate, a sample of liquid for which viscosity is desired to be determined. The dispensed liquid flows through a flow through miniature viscosity sensor having at least two pressure sensors which measure the pressure drop of the liquid as it flows through a rectangular flow channel, the pressure drop at the known flow rate being proportional to the viscosity. A controller controls operation of the viscometer and processes sensor data, and the resulting measurements of viscosity can be displayed on a display. The positive displacement pipette is removably positioned in the viscometer so that it can be removed from the viscometer when a viscosity test is completed and replaced with another positive displacement pipette containing another liquid to be tested.Type: GrantFiled: April 26, 2011Date of Patent: October 22, 2019Assignee: RheoSense, Inc.Inventor: Seong-Gi Baek
