摘要： An apparatus and a method for measuring fluid viscosity are revealed. An inlet end of a container is larger than an outlet end of the container. A fluid flows through the outlet end at a flow rate. A volume of the fluid flowing out of the outlet end is measured by a graduated cylinder while the time taken for the fluid to flow through the outlet end is measured by a timer. The flow rate is associated with the volume and the time of the fluid and the viscosity of the fluid is obtained according to a density and a pressure gradient of the fluid, an outlet end radius and the flow rate. The apparatus has simple structure, easy operation and maintenance. Moreover, less space is required and the apparatus cost is low. Therefore, the testability is improved, the measurement time is reduced, and the convenience in use is enhanced.

摘要： An apparatus for measuring viscosity includes a container in which an inlet radius of an inlet end is larger than an outlet radius of an outlet end. A fluid with a flow velocity is placed in the container. The fluid has a density value and a pressure gradient value. A pressure controller for controlling the pressure gradient value of the fluid is connected to the inlet end and the outlet end. A flow meter measures the flow velocity. A viscosity of the fluid is correlated with the density value, the pressure gradient value, the inlet radius, the outlet radius and the flow velocity. After being applied to various fluids, the present invention improves testability. Moreover, the measurement time is reduced due to simple structure. The maintenance is easy and the operation is not complicated. Furthermore, less space is required, the cost is down and the measurement error is reduced.
