The accuracy of vortex flowmeter depends on many factors, including the model and specification of vortex flowmeter and the technical level of manufacturer. Generally speaking, the accuracy of ordinary pipeline vortex flowmeter can reach1%r1.5% r1%fs, while the plug-in vortex flowmeter can only reach 2.5% r 2.5% fs. But the actual accuracy level needs to be evaluated according to the specific use environment and measurement requirements.
