Contactless Method of Measurement of Surface Tension

Abstract

Results of studies of a contactless method of measuring surface tension are analyzed. The method is based on a determination of the degree of deformation of the surface of a test liquid subjected to the weak aerodynamic action of a gas jet. The method utilizes the property of a deformed surface to converge optical radiation. The result of a measurement by the method possesses low sensitivity to variations of the density and viscosity of the liquid.
