Problems solved by technology

The present invention is a measuring instrument designed based on the viscosity expression derived from Poiseuille's formula, mainly used for measuring the viscosity of fluid (especially gas), and adopts capillary, micro-flow meter and differential pressure gauge to measure the viscosity of fluid, with simple structure , low cost, easy to use, easy to popularize and high measurement accuracy, when using it to measure the viscosity of gas, it solves the problem that the existing gas viscometer is expensive and not easy to popularize
[0013] However, in this prior art, a flow meter and a differential pressure gauge are used to measure the fluid viscosity coefficient, and the measurement errors of the two sensors will affect the measured value, and the measured values ​​of the two sensors need to be manually recorded by the measurer, and it is difficult to record both at the same time. Data, there are systematic errors, and it is not conducive to automation

Description

technical field [0001] The invention relates to the technical field of liquid viscosity coefficient measurement, in particular to a comprehensive measurement platform for measuring liquid viscosity coefficient and a measurement method for measuring liquid viscosity coefficient using the measurement platform. Background technique [0002] When there is relative motion between various parts in the liquid, the internal friction force between the contact surfaces produced by van der Waals force, hydrogen bond force, etc. is viscous force. The viscous force will hinder the flow trend of the liquid, and its magnitude is proportional to the area of ​​the contact surface and the velocity gradient at the contact surface, and the proportional coefficient is the viscosity coefficient. In the field of industrial production, the viscosity coefficient of lubricating oil affects the efficiency of mechanical transmission; in the field of medical and health care, the viscosity coefficient of...
