Dwyer SFI-100T-3/4-A711T | Sight Flow Indicator & Transmitter | 3-35 GPM (11.4-132.5 LPM), 3/4" NPT
The Dwyer SFI-100T-3/4-A711T pairs a brass 100 Series sight flow indicator with the A-711T output sensor, covering 3-35 GPM (11.4-132.5 LPM) through a 3/4" female NPT connection. Flow is checked by eye at the window while the sensor sends pulses, proportional in frequency to flow, for remote monitoring.
- Range 3-35 GPM (11.4-132.5 LPM) with 3/4" female NPT process connection
- Two pulsed outputs on the 3/4" model: 5 VDC (white lead) and supply voltage (green lead), 0 to 100 Hz
- SFI-100T-3/4-A711T powered from 8 to 28 VDC; accuracy +/-5% of full scale
- Wetted parts on the 3/4" unit: brass body, tempered glass window, UV-stabilised PBT rotor, 316 SS rotor pin, Buna-N gasket
- Rated 125 psi (8.62 bar), -20 to 200°F (-29 to 93°C); horizontal mounting for the 3/4" size
