The standard orifice flowmeter metering device is a key equipment for determining the output and quality of natural gas. The smoothness of the inner wall of the upstream and downstream measuring tubes is crucial to the accuracy and stability of the metering device. By establishing a flow field analysis model for a standard orifice flowmeter, the influence of different pipe diameters and different measuring tube roughness on the orifice metering accuracy is quantitatively analyzed, and the excitation vibration descaling device is optimized and designed. The optimal operating conditions are determined through experimental research, and the effectiveness of the measuring tube maintenance method is proved. This new device can effectively ensure the safety, efficiency, and standardization of the natural gas metering system, reduce the labor intensity of employees, and reduce the cost of operation and maintenance. It has a good safety effect and a broad application prospect.
