METHOD OF DETERMINING SURFACE TENSION OF LIQUID Russian patent published in 1994 - IPC

Abstract RU 2024843 C1

FIELD: measuring equipment. SUBSTANCE: liquid film is formed on a frame holder. A flexible thread made of a loop is positioned on the frame. The film is punctured inside the loop and surface tension is determined by thread deformation. The thread is made of electrically conducting rubber and resistance of the thread before and after film puncturing is measured to determine surface tension of liquid. EFFECT: enhanced accuracy. 2 dwg
