High-Temperature, High-Shear Capillary Viscometer

US Patent:
4658636, Apr 21, 1987
Filed:
Mar 18, 1986
Appl. No.:
6/842088
Inventors:
Robert E. Manning - Boalsburg PA
Wallis A. Lloyd - State College PA
Assignee:
Cannon Instrument Company - State College PA
International Classification:
G01N 1106
US Classification:
73 55
Abstract:
A high-temperature, high-shear viscometer includes a closed end tube having a chamber. A first inlet to the tube is for introducing pressurized gas therein. A second inlet to the tube is for introducing the liquid into the chamber and removing excess liquid from the chamber. A capillary tube is in communication with the chamber. An outlet for the liquid is in communication with the capillary tube. A timer is provided for measuring the efflux time of the liquid in the capillary tube. The timer is started by a device in communication with the first inlet. The timer is stopped by a device which senses the movement of the pressurized gas.
