LUGB Vortex Flowmeter

Vortex flowmeter is a kind of flowmeter based on the principle of Karman vortex street, used to measure the flow of liquid, gas and steam, as well as turbid liquid containing tiny particles and impurities. It is widely applied in petroleum, chemical, pharmaceutical, papermaking, metallurgy, electric power, environmental protection, food and other industries.

 

√ It can be used to measure the flow of liquid, gas and steam

√ The protection level can reach IP68

√ The highest measurable medium temperature can reach 420℃

√ The SF30 three-wire system supports Bluetooth to set parameters within 20 meters, which is convenient for on-site operation

√ Turn down: 10:1
