技術說明

本發明之黏度之量測裝置包含一容器，容器設有一入口端與一出口端，入口端之一入口端半徑大於出口端之一出口端半徑，一流體設於容器內，流體於容器內具有一流速，流體具有一密度值與一壓力梯度值，一壓力控制裝置接設於入口端與出口端並控制流體之壓力梯度值，一流速計量測流速，流體之一黏度值相關於密度值、壓力梯度值、入口端半徑、出口端半徑與流速。本發明適用於不同之流體，不但提高可測試性，且本發明之量測結構簡單，可降低測定黏度值之時間，因此維護容易且操作複雜度低，不但不佔用空間，且可降低儀器成本，亦可減少量測誤差值。 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 completed. Furthermore, less space is required, the cost is down and the measurement error is reduced.
