Problems solved by technology

Although the water tunnel test device is a general-purpose device for fluid mechanics test research, it has the disadvantages of relatively large equipment size, relatively large space occupation, high power of the power system driving water flow, and high energy consumption and test costs.

If the test device is made according to 1:1, the production cycle is longer, the production cost is high, and the installation and testing of the measuring components during the test is not convenient enough
