FKMF SeriesIn comparison to the glass tube rotameters, metal tube rotameters are compatible with much higher temperature and pressure and render superior mechanical strength and durability. Features: - No need for straight pipe section upstream - High accuracy, repeatability and linearity - Can be used for liquid, gas and steam - Low cost compared to other types - Ease of installation and replacement - High pressure compatibility - Chemical compatibility - Wide selection of connection types(Flange, PT, NPT, ANSI, JIS, etc.) - Wide selection of materials(306 SS, 316 SS, Metal, etc.) - Wide choice of options(Control valve, strainer, digital ouput, cooling fin, damper, heating jacket, etc.) - High accuracy, repeatability and linearity
