Introducing the MFI series flowmeter, a robust and versatile metallic rotameter, perfect for accurately measuring liquids, gases, and steam. In this advanced device, a magnetic float precisely aligns with a unique position within the measuring tube for each flow rate of the medium. This position integrates seamlessly with the indicator's magnetic system through an embedded magnet, allowing the user to effortlessly read the corresponding flow rate on the dial and pointer. Specifically crafted for vertical piping with a bottom-in, top-out flow, the standard rotameter can be customized with specialized structures to suit diverse applications. The MFI series is trusted across industries like petrochemicals, chemicals, fertilizers, metallurgy, power, food, pharmaceuticals, and papermaking, offering precise measurement and process control for liquids, gases, and steam.
