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
