Model L PTFE-PFA flow meters

Model L PTFE-PFA for low to medium flow range measurements

Downloads

Incorporating the principles of traditional rotameter flow technology, these rugged PTFE-PFA flow meters offer solutions to low to medium flow range measurements from 5 mL/min to 45 L/min of highly corrosive or ultra-pure liquids. Model L Meters are constructed of inert materials such as PFA, PTFE and PCTFE. The 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 panel nuts.
