Incorporating the principles of traditional rotameter flow technology, these rugged PTFE-PFA flow meters offer solutions to low to medium flow range measurements of highly corrosive or ultra-pure liquids. Model L Meters are constructed of inert materials such as PFA, PTFE and PCTFE. Wetted inert components are surrounded by structurally rigid materials such as PFA-clad aluminum, KYNAR® . The resultant design represents a unique combination of a rugged mechanically rigid frame and the chemically inert wetted parts. Flow meters are also resistant to external, ambient corrosives. For the protection of personnel each flow meter is supplied with a safety shield. Flow meters are supplied with or without built-in needle valves and they are panel mountable, by means of KYNAR® panel nuts.
