Air Flow Rotameter Metal Tube Float Variable Area Flow Meter
Air Flow Rotameter Description:
NYGZ-L series metal tube rotameter has simple structure, reliable operation, high accuracy and wide application range. Can withstand higher pressures than glass rotameters. NYGZ-L series flowmeters have local indication, electric remote transmission, limit switch alarm, corrosion resistance, jacket type, damping type and explosion-proof varieties. It is widely used in the measurement and automatic control of liquid and gas flow in national defense, chemical industry, petroleum, metallurgy, electric power, environmental protection, medicine and light industry and other departments.
Some parts of the flowmeter detection are made of 1Cr18Ni9Ti stainless steel material, and can also be composed of corrosion-resistant materials such as Cr18Ni12Mo2Ti or F46 in special occasions. Except for special specifications, the height of the flowmeter is 250 mm. The connecting flange adopts GB/T9119.8～10 standard, and can also be customized according to the special requirements of users
