In order to check if the viscometer meets the standard, a constant calibration of the capillary viscometer must be performed. The constant of a capillary viscometer is determined by measuring the time a quantity of liquid passes through a fixed capillary viscometer under the force of gravity at a constant temperature, and dividing the time by the viscosity value of the sample liquid to give the viscometer constant.

In the measurement process, the capillary viscometer needs to be placed in a constant temperature tank, the perpendicularity of the capillary viscometer is firstly adjusted, and the capillary viscometer is adjusted to be perpendicular in two mutually-angled directions by using a wire pendant. However, the resolution of human eyes is limited, the human eyes are different, certain verticality errors exist, and the process of manually adjusting the verticality is tedious, time-consuming and labor-consuming, and directly affects the detection efficiency and accuracy.

With the development of sensor technology, how to use the sensor to perform the application of the automatic perpendicularity adjustment technology in the detection process of the capillary viscometer is more important.
