DEVICE FOR MEASURING FLUID VISCOSITY

摘要

PURPOSE: A device for measuring fluid viscosity is provided to easily measure the viscosity of fluid by detecting a movement change of a fluid boundary face. CONSTITUTION: A device(100) for measuring fluid viscosity comprises a first channel part(120), a second channel part(130), and a third channel part(140). First fluid, which is required for measuring viscosity, flows in the first channel part. Second fluid, which is not mixed with the first fluid, flows in the second channel part. The first and second channel parts are symmetrical to each other. The third channel part connects the first and second channel parts. The cross section of the third channel part is smaller than the cross sections of the first and second channel parts.
