Description

Technical Field

[0001] The utility model belongs to the technical field of flow meters, and more specifically, particularly relates to a portable turnover universal flow meter device. Background Art

[0002] In the gas supply industry, industrial and commercial users are an important customer group of gas companies. The accurate measurement of their gas consumption is not only related to the company's economic benefits, but also directly affects the gas consumption costs and satisfaction of users. Therefore, as a key device for measuring user gas consumption, the accuracy and reliability of gas flow meters are particularly important.

[0003] Based on the findings in the prior art, when the existing flow meters are in use, the flow meters need to be calibrated after a certain number of years of use, which usually involves the disassembly, inspection and reinstallation of the equipment. The process is cumbersome and time-consuming, which has a great impact on the normal gas use of users. At the same time, in order to deal with this problem, gas companies often need to invest a lot of money to purchase spare gas meters for replacement, which undoubtedly increases the company's operating costs. In addition, the flow meters are fixed with bolts during installation and cannot be quickly installed and disassembled, resulting in poor work efficiency. Since there are no unified specifications for the size of gas meters in national standards and industry standards, the sizes and interfaces of flow meters produced by many flow meter manufacturers are also different. Even if the meter types and pipe diameters of the same manufacturer are different, the length dimensions of the meters are also different. Since the size of the meter access position on the gas pipeline is fixed, it is impossible to achieve connection with pipelines of different specifications. If the bolts are loose when connecting the pipelines, leakage will occur, and the sealing between the pipelines is poor. Utility Model Content
