METHOD OF CHECKING PHYSICAL AND MECHANICAL PROPERTIES OF LIQUID BY ITS VIBRATIONS Russian patent published in 2002 - IPC

FIELD: testing facilities and methods. SUBSTANCE: invention is designed for checking complex of physical and mechanical properties of viscous inflammable aggressive liquids under fire and explosion hazard conditions. According to proposed method, nozzle is dipped to required depth into medium to be checked, flow rate of gas is changed and acoustic vibrations frequency is measured basing on which surface tension is judged at moment of beginning of vibrations in liquid. EFFECT: provision of efficient checking of surface tension. 1 dwg
