VISCOSITY MEASUREMENT DEVICE OF GAS

摘要

The present invention relates to an apparatus to measure a viscosity of gas. The apparatus comprises: a body unit configured to form a closed space in which gas flowing in an internal space thereof is disconnected from the outside; a flow motion generating unit installed inside the body unit, including a rounded flat plate and a rotating means rotate-coupled to a center of the flat plate to rotate the flat plate, generating a flow motion due to the viscosity of gas contacting a surface of the flat plate during the rotation of the flat plate; a measuring unit installed inside the body unit, including a rod cell having one end portion disposed on a space adjacent to the flat plate in a direction perpendicular to a rotating direction of the flat plate, and an other end portion fixated to one side of an inside of the body unit, measuring a force of gas acting on the rod cell; and a display control unit calculating and providing a measured force value due to the flow motion of gas measured through the rod cell of the measuring unit.
