It is well known that the vortex flowmeter based on piezoelectric effect widely used in flow measuring applications is sensitive to the vibration of the pipeline where it locates, which brings detection errors. In order to study the pipeline vibration influence on the measuring accuracy of the vortex flowmeter, a number of experiments under the gas flow rate in the rang from 35m3/h to 145 m3/h have been carried out on the application-specific pipe vibrating facility, where the vibration parameters can be configured ( vibrating acceleration：0.05g, 0.1g, 0.2g, 0.5g, 1g; vibrating frequency: 40Hz, 100 Hz, 200 Hz; vibrating direction: vertical and horizontal ). The pipeline vibration influence and the anti-vibration performance of the vortex flowmeter are evaluated in terms of its meter coefficient. The results show that with an increase in vibrating acceleration, there is an increase in the meter coefficient error; with an increase either in vibrating frequency or flow rate at the same vibrating acceleration, there is a decrease in the meter coefficient error; and smaller influence on the measuring accuracy is caused by the horizontal-oriented pipeline vibration compared with the vertical-oriented one.
