Problems solved by technology

In actual operation, the experiment cannot be carried out because the beam is too narrow to catch the ball
The main reasons for this phenomenon are: 1. The measuring cylinder is not strictly vertical, that is, the base is not flat; 2. The initial velocity of the ball has a lateral component; 3. The ball drifts laterally due to resistance in the viscous fluid

Abstract

The invention relates to a viscosity meter, especially to a laser surface capture type measuring apparatus for a viscosity coefficient. The laser surface capture type measuring apparatus comprises a container (1), a first laser transmitter (2), a second laser transmitter (3), a conduit (4), a first laser receiver (5), a second laser receiver (6), a one-chip microcomputer (7), a support (8) and a base (9). The apparatus is characterized in that strip-shaped laser source receivers (10) extending along a horizontal direction are arranged on the first laser receiver (5) and the second laser receiver (6), and laser source transmitting terminals (11) of the first laser transmitter (2) and the second laser transmitter (3) directly transmit laser to the laser source receivers (10) of the first laser receiver (5) and the second laser receiver (6).

Description

technical field [0001] The invention relates to a viscosity measuring instrument, in particular to a laser surface capture type liquid viscosity measuring device and method. Background technique [0002] The viscosity of a liquid is a measure of its viscosity. In industrial and agricultural production and scientific research, it is often necessary to know the viscosity of a liquid. There are various methods to measure viscosity. At present, the falling ball method is used in university experimental teaching. The traditional way is to measure viscosity by visual inspection. However, this brings a lot of human error and is not suitable for teaching experiments. [0003] The falling ball method to measure the viscosity coefficient is the main viscosity coefficient measurement method adopted by domestic colleges and universities. Relatively speaking, the laser measurement method adopted is a more accurate measurement method. [0004] The laser measurement method of the viscosi...
