Dwyer SFI-800-1/2-A711 | Polysulfone Sight Flow Indicator with A-711 Sensor | 2-20 GPM, 1/2" female NPT
Part Number : SFI-800-1/2-A711
The Dwyer SFI-800-1/2-A711 pairs a polysulfone rotor-type sight flow indicator with the A-711 Hall Effect sensor for remote monitoring, covering 2-20 GPM (7.6-75.5 LPM) through a 1/2" female NPT connection. On the SFI-800-1/2-A711, the A-711 gives two pulsed voltage signals with frequency proportional to flow rate.
- 2-20 GPM (7.6-75.5 LPM) flow range on the SFI-800-1/2-A711, ±5% FS accuracy
- SFI-800-1/2-A711 pulse output 0 to 100 Hz: white lead 5 VDC, green lead 8 to 28 VDC
- Supply of 8 to 28 VDC on the red lead, ground on black (SFI-800-1/2-A711)
- Polysulfone body and window, a white polysulfone rotor and an NSF-grade fluoroelastomer O-ring; 316 SS rotor pin (1/2" model)
- SFI-800-1/2-A711 rated to 150 psi (10.34 bar) and -20 to 212°F (-29 to 100°C); max viscosity 200 SSU
