Control devices manufactures offers on-line metallic body rotameters. These rotameters , which are used to measure high ranges of flow with high pressure. These rotameters can be applied used in critical/corrosive atmosphere where it is not possible to use conventional rotameters.These rotameters they are made from stainless steel [either ss 304 or ss 316] with magnetic float and stainless steel end connections. Due to their rigid construction, these rotameters y can withstand higher pressures and temperatures and . They are ideal for chemicals and other fluids, which react to ordinary rotameters. Ranges are offered from 0 to 230,000 lpm for gases and 800 lpm liquids ranges are offered from 0 to 230,000 lpm.
