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?
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 ?
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.

Hello, Is it possible to use this in a vertical apllication (the chemical flowing straight up with a peristaltic pump)? Can this meter be used to detect lack of feed? Also, can it handle 15% sodium hypochlorite? Thank you
Thank you for your inquiry about the flow meter series. The flow meter can work in a vertical position and the flow must be pressurized and constant, not pulsating. It can meausre the flow rate of the liquid passing and as a courtesy, chemical compatibility is the responsibility of customers to check the liquid against the wetted materials of the flow meter. The flow meters in this series are chemically compatible.
