Dwyer Instruments SFI-100T-3/4-A711T | Brass sight flow indicator with A-711T sensor | Range 3-35 GPM (11.4-132.5 LPM) | 3/4" female NPT
The SFI-100T-3/4-A711T Model Sight Flow Indicators & Transmitters is an affordable and robust flow transmitter that combines our A-711T output sensor with our well-liked 100 Series Sight Flow Indicator to provide both visible and remote flow monitoring. Two pulsed voltage signals are available for the A-711T output sensor: one pulses at 5 VDC, while the other pulses at the input supply voltage, which can be anywhere between 8 and 28 VDC. The pulsed output of the sensor changes frequency in direct proportion to the flow rate.
