ABSTRACT OF THE DISCLOSURE 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.
