PTFE-PFA | model L Aalborg Instruments

Product Summary
model L rugged PTFE-PFA flow meters offer solutions to low to medium flow range measurements

Design Features

- chemically inert wetted components constructed from PFA PTFE and PCTE
- non-fluid contacting structurally rigid frame constructed from PFA-clad aluminum and KYNAR®.
- overlapping flow ranges are available for water from 5 mLPM (0.00132 GPM) to 45 LPM (12 GPM).
- individually leak tested

Rugged Model L PTFE-PFA flow meters incorporate the principles of traditional rotameter flow technology They offer solutions to low to medium flow range measurements of highly corrosive or ultra-pure liquids. 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.
