Product Specs

The FPR300 Series comprises versatile impeller flow meters in 3/8 to 1" nominal pipe size that employ jewel bearings for very low minimum flows. The 6 to 24 Vdc pulse output of these meters is compatible with many different types of control, including a full range of OMEGA rate displays and controls. The FPR300 Series body material is polypropylene, with transparent acrylic covers for visual flow indication. Polypropylene covers are available as an option. The FPR310 Series has TFE housing, TFE cover (not visual), PVDF rotor, and a ceramic shaft.

Hi, Is it possible to use this meter with high viscous liquids like Antifrogen N?

Asked by: Yuxel
Thank you for your inquiry. Unfortunately, this flow meter has a limitation on viscosity. Best suggestion would be to use a positive displacement flow meter for any viscous liquids since it is independent of viscosity changes.

Can these be piped in vertical down flow ?

Asked by: Mennis
Thank you for your inquiry. Unfortunately, that will not be ideal, horizontal position is preferred. Although, in a vertical position, flow must go from floor to the ceiling to ensure full flow of pipe, if not, it will not be suitable for any of our flow meters.
