Vortex flowmeter maximum size could reach DN300 means 12inches diameter. The more large size will suggest using an insertion-type vortex flow meter.
A large-caliber vortex flowmeter is a measuring instrument with high measurement accuracy, simple installation, small maintenance, and a wide range of uses. It is currently widely used in Oil, chemical, metallurgy, textile, urban construction, energy, and other industries.
The following is the diameter of a vortex flowmeter in liquid and gas application, also the vortex flowmeter measuring range for reference.
