摘要： A system and method for measuring physical properties of non-Newtonian fluids, such as fluids containing dispersed solid particulate material and having a yield stress. A fluid resistance member is moved through the non-Newtonian fluid sufficiently slowly that viscous drag on the member is negligible and fluid resistance is essentially due to the yield stress of the fluid. The torque required to maintain the movement of the member through the fluid is measured, and at least one physical property, other than apparent viscosity of the fluid, is determined by employing a known relationship between the measured torque and the physical property of interest.

摘要： A method of determining viscosity of structurally viscous fluids or beverages containing small pieces, fibers, pulps, fruit cells, cereals, particles or the like, for processing in filling, fruit juice preparation, dairy or brewery process plants, includes providing a tube rheometer having an at least substantially horizontal, straight meter tube with an inner diameter over a length of the meter tube length. At least two different volume flows are generated, exclusively gravimetrically, in the tube rheometer. The at least two different volume flows are adjusted to be substantially constant so as to determine a flow index and a consistency factor of the at least two volume flows. Pressure losses of the at least two volume flows are measured. The viscosity is determined based on the flow index, the consistency factor and the pressure losses.

摘要： A rigid, planar, non-resonating boundary is introduced parallel to the surface of the piezoelectric resonator in a measurand chamber in order to both reduce the separation space (l) between the resonator and confining wall and confine the measurand fluid between those surfaces in order to reliably measure acoustic viscosity independently form the mass density (ρ) of the measurand fluid. The hypothesis is that when the penetration depth (δ) is comparable to the separation distance (l) between the resonator and the confining wall, then resonator perturbation is a sensitive function of the abbreviated separation space. Variations in the spacing between the resonator and confining wall are accomplished by adjusting the rigid, planar, non-resonating boundary, or confining wall, with a means for lateral movement. The ability to accurately adjust and control small spaces thereby enables MEMS versions of viscometers and associated types of fluid sensors.

摘要： A sensor for making rheological measurements takes the form of a ferromagnetic bob alternately driven through a sample fluid in opposite directions by magnetic force from two alternately driven coils. The bob's position affects the mutual inductance between the coils, so it can be inferred by sensing the signal that current flowing in one coil induces in the other, and rheological properties are determined from the relationships among the bob's motion, the coil current, and the sensor geometry. Some such measurements' accuracies are enhanced by computing bob acceleration and suppressing inertial effects thereby detected.

摘要： A nanoliter rheometer is capable of operating over a wide range of temperatures and permits visual observation of extremely small amounts of various often complex and/or expensive small nanoliter size fluids over a wide viscoelastic regime. The nanoliter rheometer comprises two very thin fibers, the ends of which are in close proximity to one another and desirably parallel to one another with one fiber being moved by a drive system and the remaining fiber desirably being stationary and capable of measuring a force transferred through a nanoliter size fluid located between the two fibers ends. The transferred force can be measured either by an LCR meter or a piezoelectric crystal and recorded as by a lock-in amplifier.
