Capillary viscometry 毛细管粘度计
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.
毛细管粘度计
毛细管粘度计是用于液体的粘度与牛顿流动特性的确定*准确的方法。测量本身是由一个时间测量。测定的时间是毛细管的特定数量液体通过具有特定宽度和长度的毛细管。通常，这个过程被用人眼来观测，并用秒表手动测量流动时间。
在UVS MD自动粘度测量装置是用光电方式或者基于热敏电阻的热抗性来测量液体凹面。
