초록 ▼

A viscometer assembly includes a first plate with a rail configured to constrain fluid thereon between its edges by surface tension. A second opposing plate has a surface spaced from the rail by a predefined gap of constraining fluid to the rail by surface tension when the rail is inclined and gravity pulls the fluid along the rail. The kinematic viscosity of the fluid is determined as a function of the predetermined gap and the time it takes the fluid to flow along the rail.

대표청구항 ▼

1. A method of determining the kinematic viscosity of a fluid, the method comprising: constraining a sample of the fluid to flow in a gap between a rail and a surface spaced from the rail;measuring the time it takes the fluid sample to flow between two defined locations on the rail;determining, based on the time, the velocity of the fluid sample; andbased on the velocity, calculating the kinematic viscosity of the fluid sample. 2. The method of claim 1 in which calculating includes using an equation wherein the kinematic viscosity is a function of the gap and the velocity. 3. The method of claim 1 further including heating the fluid. 4. A method of determining the kinematic viscosity of a fluid, the method comprising: constraining a sample of the fluid to flow in a gap between a rail and a surface over the rail;determining the velocity of the fluid sample as it flows along the rail; andbased on the velocity, calculating the kinematic viscosity of the fluid sample. 5. The method of claim 4 in which determining the velocity includes measuring the time it takes the fluid sample to flow between two defined locations on the rail. 6. The method of claim 4 in which calculating the kinematic viscosity of the fluid sample includes using an equation wherein the kinematic velocity is a function of the gap and the velocity. 7. A method of manufacturing a viscometer, the method comprising: including on one surface a rail configured to constrain fluid thereon between its edges by surface tension;providing a second surface spaced from the rail by a predefined gap for constraining fluid to the rail by surface tension when the rail is inclined and gravity pulls the fluid along the rail; andreleasably coupling the second surface over the rail. 8. The method of claim 7 including adding kinematic mounts to provide the predefined gap. 9. The method of claim 7 including providing at least one magnet for releasably coupling the second surface over the rail. 10. The method of claim 7 including forming raised lands spaced from and on opposite sides of the rail. 11. The method of claim 7 including providing a well adjacent to the rail. 12. The method of claim 11 including dividing the rail into split fingers on opposite sides of a ramp defining the well. 13. The method of claim 7 further including providing a heater which heats the fluid.
