摘要： Disclosed is a method for measuring changes in a physical property of a liquid or semisolid material which comprises placing a thin metal wire in the material; passing an electric current through the thin metal wire in such a way that the temperature difference between the material and the thin metal wire is kept constant; measuring the intensity of the electric current; and calculating the heat transfer coefficient at the surface of the thin metal wire on the basis of the measured intensity of the electric current and thereby detecting changes in a physical property of the material. This method makes it possible to detect, for example, changes in the coefficient of kinematic viscosity of a food having the form of a gel or changes in the condition of thrombus formation in a blood vessel.

摘要： The temperature of one or several sensors which are electrically heated or cooled to a temperature substantially different from a stagnant or running fluid surrounding the said sensor or sensors by applying an electric current to the said sensor or sensors, and the temperature of the said fluid are measured simultaneously to calculate the temperature difference between the said sensor or sensors and the said fluid at an equilibrium state of heat transfer at the surface of the said sensor or sensors, thereby measuring a change in state of the said fluid collectively on an in-line processing basis without disturbing the said fluid; a change in this state results in a change in heat transfer coefficient at the surface of the said sensor or sensors, the coefficient being collectively correlated with the viscosity, density, specific heat, thermal conductivity, thermal diffusivity, coefficient of volumetric expansion, flow speed or flow direction of the said fluid at a given temperature.

摘要： A heat-generating element and a fluid temperature measuring element are immersed in a molten or gelled fluid sample to measure continuously both temperature .SIGMA.w of the said heat-generating element and fluid temperature .THETA..infin. during the cooling or heating of the fluid sample at one or several constant cooling or heating rates. An abrupt change in .THETA.w-.THETA..infin. value is detected to obtain the practical gel-point temperature of a characteristic gel-point temperature, which is defined as the extrapolated gel-point temperature at a cooling or heating rate of zero.

摘要： A heating sensor is disposed within a pipe with a clearance between an inner wall of the pipe and an outer surface of the heating sensor such that a measurement of thermal conductivity is free from any influence of a convective heat transfer. Temperatures of the fluid and the heating sensor are measured and a differential temperature therebetween in steady state heating is determined. A correlation is established between the differential temperature and a thermal conductivity of the fluid and is utilized to obtain the thermal conductivity of this fluid.

摘要： In a subject fluid, there is placed an apparatus for measuring a change in state of the fluid, said apparatus having a tubular body which, in turn, contains therein at least one heating sensor employing so-called hot wire method. A quantity of the fluid is introduced into the tubular body and a temperature of the heating sensor is measured by the heating sensor itself as the quantity of the fluid having been introduced into the tubular body is maintained in a state of laminar flow or a static state. The laminar flow is generated by fluid impeller means such as impeller vane, screw-type vane or propeller vane assembly or uniaxial eccentric pump. The static state is maintained y providing gateway means for passage of the fluid into or out from the tubular body and closing such gateway means. A temperature of the fluid having been introduced into the tubular body and maintained in said laminar or static state is measured and discharged out from the tubular body upon completion of said temperature measurements. A change in state of the fluid is determined based on the temperatures of the fluid and the heating sensor.
