The model F is a variable-area flow meter constructed either from Polytetrafluoroethylene or Polychlorotrifluoroethylene material. It is an inline rotameter that is specially designed for medium flow rates. This flow meter consists of chemically inert parts that can be submerged and a protective shield that can be easily detached. Each flow meter is tested for possible leaks and is able to adopt to flow rates that range from 125 mLPM to 45 LPM water. This is an ideal device to be used in high-purity operations and with corrosive substances as well. It is integrated with a modular valve that monitors and regulates flow.
