Innovative bubble method and means of control

Abstract. A new principle of measuring the viscosity of the fluid based on the control parameters of motion of a gas bubble in a viscous medium. A mathematical model and a measurement tool to monitor the dynamics of changes in the viscosity-temperature parameter bubble environment. An experimental study of the changes in the rheological properties of the process of development of lactic acid bacteria Lactobacillus plantarum on a nutrient medium. The experimental dependence of the viscosity of the medium on the concentration of the aqueous solution of sugar.
