ABSTRACT:
A constant output pump delivers a portion of a fluid, the viscosity of which is to be controlled, into a measuring capillary tube to develop a pressure differential across the measuring capillary tube. Means are provided to sense the pressure differential and control the fluid viscosity in response thereto. A second capillary tube is adapted to receive all of the fluid discharged from the measuring capillary tube and an elastic fluid space is interposed between the measuring capillary tube and the second capillary tube. The flow resistance of the second capillary tube and the elasticity of the fluid space functions to make the pressure differential independent of static fluid pressure changes.
