  • Method and apparatus for measuring the elasticity of fluids
    Patent number: 6711940
    Abstract: An indication of the elasticity of a non-Newtonian fluid is obtained by extending a fluid bridge between a pair of relatively movable surfaces that hold a fluid sample therebetween, and continuing a timewise progression of separation between two opposed moveable surfaces in a controlled manner until the displacing extension is great enough to cause a break point in the fluid sample. The extension of a fluid bridge at the break point is determined and used as an indication of elasticity.
