Series SFI-100T Sight Flow Indicator/Transmitter

Output for Flow Rate and Totalization

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.

Product Applications

Monitor chilled or hot water flow
Monitoring water flow in chillers
Cooling and lubrication circuits
HVAC systems

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
