Problems solved by technology

As a general-purpose equipment for fluid mechanics test research, the water tunnel equipment has a large size and takes up a lot of space. The power system driving the water flow is very powerful, and the energy consumption and test cost are very high. If the test device is made according to 1:1, the production The cycle is long, the production cost is high, and the installation and testing of the measuring elements during the test are not convenient enough
