The Model V PTFE is a single flow tube rotameter, suitable for medium flow rate measurement. In terms of features, the compact construction is a rigid one, while the item ensures dual rotatable direct reading scales for water and air. There are two versions available, a vertical in-line or a panel mount, while the graduations reflect the English or metric systems.

The flow ranges from 3 to 4LPM water, as well as 100 to 623LPM air. Note that these products incorporate traditional rotameter precision glass technologies, while the rugged PTFE flow meters offer an economical and accurate solution for medium flow range measurements. The V meters are designed with unique rotatable scales or dual air-water, while the direct reading graduations show the SCFM and SLPM markings.
