Series SFI-100T Sight Flow Indicator/Transmitter

Brand: Dwyer Instruments, LLC

The Series SFI-100T Sight Flow Indicators & Transmitters is a low cost and durable flow transmitter that combines our popular 100 Series Sight Flow Indicator with our A-711T output sensor for visual and remote monitoring of flow.

The A-711T output sensor has two pulsed voltage signals with one providing a 5 VDC pulse, the other a pulse of the input supply voltage used, ranging from 8 to 28 VDC and a pulsed output with a frequency change proportional to the flow rate.
Features
  • Constructed of a robust, solid brass body and a tempered glass window
  • Bright red impeller yields great visual indication of flow through the window
  • Front window can be easily unscrewed to clean out the sight flow indicator
  • Ideal for outdoor applications with weatherproof body that is unaffected by UV Light
