Instruments in this company’s PTFE/PFA Model L range of rotameters (photo) are constructed of rigid frames and inert wetted parts. Made of perfluoroalkoxy alkanes (PFA), polytetrafluoroethylene (PTFE) and polychlorotrifluoroethylene (PCTFE), the meters are resistant to ambient corrosive media. Constructed with or without built-in needle valves, L Meters are easily mountable via panel nuts. Units are individually leak tested. For personnel safety, each L Meter is supplied with a safety shield. Overlapping flow ranges are available for water from 5 mL/min to 45 L/min. The maximum operating pressure is 6.7 bars, and the maximum operating temperature is 250°F. — Aalborg Instruments, Orange, N.Y.
