Capillary viscometry is the most accurate method for the determination of the viscosity of liquids with a Newtonian flowing behaviour. The measurement as such consists in a time measurement. The time measured is that which a specific quantity of liquid requires to pass through a capillary having a defined width and length. Conventionally, this process is watched with the human eye, and the flow time is measured manually using a stop watch.
In the case of the UVS MD Viscosity Measuring Device, the liquid meniscus is captured on the measurement planes, either in an optoelectronic manner by means of light barriers, or else on a thermo-resistant basis by thermistors.
毛細管粘度計
毛細管粘度計是用于液體的粘度與牛頓流動特性的確定*準確的方法。測量本身是由一個時間測量。測定的時間是毛細管的特定數量液體通過具有特定寬度和長度的毛細管。通常，這個過程被用人眼來觀測，并用秒表手動測量流動時間。
在UVS MD自動粘度測量裝置是用光電方式或者基于熱敏電阻的熱抗性來測量液體凹面。
