Description
For Vertical Pipe Installation
F-300 Features– Determine circulation system flow rate in seconds- Installs quickly- One-piece machined acrylic meter body, polished to a clear finish- East-to-read, high resolution dual scale, permanently printed- Read flow from either side of the meter body- Ships complete with gasket seal and mounting clamps
New and Improved F-300 Features
– The F-300’s new aerodynamic pilot tube, allows for smooth flow of the water through the pilot tube and meter, resulting in no float bounce and improve accuracy to ±5%- The new red PVDF float is non-stick and chemical resistant. The bright red color greatly enhances meter readability- New, optional F-300S flow switch accessory available- The new design requires only half the straight pipe run, making these meters an excellent choice for cramped equipment rooms- The signature red cap is now manufactured from a new material that resists fading and cracking
