  • Apparatus and method for measuring viscosity
    Patent number: 7237431
    Abstract: An apparatus and methods for analysis of a petroleum product, specifically determining the viscosity of a sample, are disclose. The apparatus includes a sample reservoir for receiving a liquid sample and a pressure regulator for applying hyperbaric pressure to a sample within the reservoir. When pressure is applied to the sample reservoir, the sample is forced through a passageway and a pressure sensor monitors the pressure in the sample reservoir. A drop in the pressure can be used to determine when the reservoir is empty and sample viscosity can be calculated based on the time required to empty the reservoir.
