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. The flow meter often needs to work in the open air and other environments, and water such as rainwater and steam will cause certain damage to the flow meter. It is a technical problem to be solved urgently by those skilled in the art to develop a flow meter that can overcome the above defects.

Embodiment 1

[0049] A flow meter with a protective cover provided in this embodiment has a structure such as Figure 1-4 As shown, it includes the flow meter head 1 and the flow tube. The flow tube is a hollow tubular structure. The flow tube is connected by the liquid inlet pipe 2 and the liquid outlet pipe 3. The flow meter head 1 is located in the middle of the flow tube length direction. The flow meter The head 1 is also covered with a protective cover, wherein:

[0050] The protective cover includes a protective cover body 4, a water guide groove arranged on the protective cover body 4 and an adapter 6. The protective cover body 4 is composed of five plates, and at least one side plate of the protective cover body 4 is movably connected to the protective cover. On the body 4, the two sides of the protective cover body 4 are respectively provided with nozzles for the liquid inlet pipe 2 and the liquid outlet pipe 3 to extend into, and the upper end of the protective cover body (4) and ...
