Problems solved by technology

[0002] The flow meter measures the instantaneous flow and cumulative volume of the liquid, and can also quantitatively control the liquid. It is widely used in industries such as industrial mining, petroleum, chemical industry, metallurgy, and electric field. When in use, most of them measure the inflow and outflow directly through the fluid. , the current water quality is relatively poor, the hardness of the water is relatively high, it is easy to form dirt, and sometimes there are some metal powders, which pose a great threat to the flow meter, and are often damaged due to water quality, and the service life is short. A kind of flow meter that can overcome the above-mentioned defects has become a technical problem to be solved urgently by those skilled in the art
