The MFI series flowmeter is a cutting-edge, all-metal rotameter exquisitely crafted for accurately measuring the flow of liquids, gases, and steam. At a given flow rate of the medium being measured, the magnetic float's position within the measuring tube is unmatched. This precise position is seamlessly linked to the indicator's magnetic system through an integrated magnet, enabling effortless reading of the corresponding flow rate from the dial and pointer. Designed primarily for vertical pipelines with a bottom-in and top-out process flow, the standard rotameter is complemented by a variety of specially crafted structures to enhance application flexibility. Esteemed across diverse industries such as petrochemicals, chemicals, fertilizers, metallurgy, power, food, pharmaceuticals, and papermaking, the MFI series metal tube rotameter excels in measuring and controlling the flow of liquids, gases, and steam for process optimization.
