[0031] As attached Figure 1 and in conjunction with the appendix Figure 2 Appendix Figure 3 Appendix Figure 4As shown: A demonstration device for showing the effect of air bubbles on the flow measurement of an electromagnetic water meter includes an inlet pipe (6), a regulating valve (2), a transparent pipe (3), a meter one (4), a meter two, an outlet pipe (1), a water tank cover (9), a handle (10), a rubber stopper (11), a display (7), a main unit (8), an outlet pipe (20), an outlet pipe seat (21), an outlet port (22), a water tank, a pressure stabilizing tank (13), a water pump (17), casters (14), a device frame (12), a drain pipe (16), an air pipe (15), and a device base plate (5).

[0032] The inlet pipe, outlet pipe, water tank, water tank cover, and outlet pipe seat are fixed to the base plate of the device.

[0033] Transparent pipe sections are installed before and after meter 1 and meter 2, allowing customers to visually observe the changes in the fluid inside the pipe.

[0034] The water tank is fixed to the base plate of the device. A water pump interface is located on the bottom side, connecting to a water pump. A pressure stabilizing tank connects the water pump to the inlet pipe to ensure fluid pressure within the pipeline. A drain pipe is located below the water tank. A water tank cover is installed on top of the water tank for easy filling. The water tank cover has a handle. An air inlet with a rubber stopper is located on the water tank cover. When needed, the stopper is removed, and the pump's suction force introduces air into the pipeline fluid (in actual use, the number of air inlets can be increased or their size adjusted as needed). An air pipe is connected below the air inlet on the water tank cover, and the outlet of the air pipe is fixed to the water pump interface of the water tank.

[0035] The outlet pipe is fixed to the base plate of the device, and the outlet pipe extends below the water surface of the pool; the regulating valves are installed at the inlet and outlet pipes, and the flow rate of the fluid in the pipes can be manually adjusted.

[0036] The device frame has doors (18) on two long sides for easy internal assembly. The two short sides can be closed or openable as needed.
