Disadvantages ：

• Relies on power supply ：The graphical display method requires power supply support, and it will not work properly once the power is cut off.
• Higher cost ：Compared with mechanical and analog display methods, the graphical display method has a higher cost and relatively complex maintenance.

5. Wireless display method

With the development of Internet of Things technology, the wireless display method has gradually become an emerging display method for oil flow meters. The wireless display method transmits flow data to remote devices for display through wireless communication technology.

Advantages ：

• High flexibility ：The wireless display method is not limited by cables, making it easy to perform flow measurement in complex environments.
• Remote monitoring ：The wireless display method supports remote monitoring, making it easy for operators to keep track of flow changes in real time.
• Data sharing ：The wireless display method supports data sharing, facilitating collaboration among multiple departments.

Disadvantages ：

• Network dependency ：The wireless display method requires stable network support, and it will not work properly once the network is interrupted.
• Higher cost ：Compared with traditional display methods, the wireless display method has a higher cost and relatively complex maintenance.

6. Hybrid display method

The hybrid display method is a comprehensive display method that combines multiple display methods, usually including mechanical, digital, and graphical display methods. By combining multiple display methods, the hybrid display method gives full play to the advantages of various display methods to meet the needs of different application scenarios.

Advantages ：

• Comprehensive functions ：The hybrid display method combines the advantages of multiple display methods, with comprehensive functions to meet the needs of different application scenarios.
• High flexibility Mixed display mode supports switching between multiple display modes, allowing operators to choose the appropriate display mode based on their actual needs.

Disadvantages ：
