<p>1,159,899. Measuring consistency of fluids electrically. TEXACO DEVELOPMENT CORP. April 25, 1968 [Aug. 4, 1967], No.19693/68. Addition to 1,120,494. Heading G1N. The viscosity of a fluid is measured by the strain developed in a stationary resilient paddle when the fluid is made to rotate round the paddle at a constant speed. As shown Fig.1, fluid flowing through a cylindrical chamber 11 from inlet 20 to outlet 22 is made to rotate about the longitudinal axis by vanes 18, 19 forming part of a rotor assembly 15 driven by a shaft 25 at constant speed. Located centrally between the sets of vanes 18, 19 is a stationary shaft 13 carrying a resilient member 12 on which are mounted resistance strain gauges. The rotating fluid bends the resilient member 12 by an amount proportional to the fluid viscosity or consistency, and measured by the strain gauges in a bridge circuit Fig.6 (not shown). Alternative constructions are described. The transducer may be used in a retroactive control system to maintain constant the consistency of a continuous grease unit.</p> |
