- Made of translucent polycarbonate that allows for good flow indication and 360-degree observation of the rotor.
- The Polysulfone used in the construction of the SFI-800 models has high ratings for pressure and temperature, good chemical compatibility, and all wetted components that meet FDA/NSF requirements for use in potable water applications.
- Because the SFI-801 versions include an easy-to-view bright red impeller and are made of UV-stabilized polycarbonate, they are perfect for outdoor applications.
- It is possible to install or change all three output packages in the field without the need for tools and without removing the body from the process line.
- The weather-tight units are ideal for usage in outdoor or washdown areas.
- The A-713 has an easy-to-use set point button that can be adjusted to the appropriate flow rate and has a red LED to show the condition of the switch.
