Flowmeter for steam
DH250 series variable area flowmeter is a kind of measuring meter which has local indication type and LCD displaying instantaneous/ accumulated flow rate, upper-limit and lower-limit alarm output, accumulative pulse output, batch control, standard two-wire 4-20mA current output, HART communi-cation, ect. Our product is good replacement of Krohne H250, ABB FAM540 and other similar rotamet- ers and widely used in the process control of industrial automation.
You may see our product is wildly used in many industries such as petrochemical, steel and iron, electric power, metallurgy, light industry, food, pharmacy and water processing of domestic China and worldwide.
Variable Area Flow meter Intelligent metal tube rotameter is a high-tech product, the use of stable, reliable and has good prospects for use.
It is mainly used in liquid, gas flow measurement and automatic control system in the oil, chemical, pharmaceutical, food and other industries.
