Technical Field

[0001] This utility model relates to the field of flow measurement technology, and in particular to an oil flow measuring instrument. Background Technology

[0002] Oil flow meters are key devices used for real-time monitoring and measurement of the flow velocity and cumulative flow of oil in pipelines. They are widely used in various stages of oil extraction, refining, storage, transportation, and sales. Their measurement accuracy and operational stability directly affect production scheduling, energy consumption control, and economic benefits. With the continuous improvement of industrial automation, higher requirements are being placed on the accuracy, response speed, and environmental adaptability of oil flow meters.

[0003] Utility model patent CN218330067U discloses a measuring instrument with a flange connection, an insulation layer, and a protective tube structure, which to some extent solves the problems of equipment damage caused by harsh weather and the impact of dust accumulation on data display. However, the cabinet and protective tube of this device are fixedly connected, and observation and operation are only possible through an opening on one side of the cabinet. When it is necessary to adjust, clean, or replace the internal measuring components, the operating space is limited, which greatly reduces maintenance efficiency and convenience. Especially in emergency situations, it may delay the handling time and affect normal operation.

[0004] Therefore, given the shortcomings of existing technologies, we urgently need a new type of oil flow meter to solve this problem. This new meter should significantly improve ease of operation and maintenance while maintaining good protective performance and measurement accuracy. It should also better meet the practical needs of the modern petroleum industry for high-efficiency, high-reliability measurement equipment, providing strong support for the intelligent development of oil transportation and management systems.
