Dwyer AFS-141 | Adjustable Flow Switch | for water, polysulfone piston, lead wires
The Dwyer AFS-141 is a piston-type adjustable flow switch for water, combining a brass housing with a polysulfone piston. The set point on the AFS-141 adjusts over 0.5 to 20 GPM (1.9 to 75.7 LPM); electrical connection is via 18 AWG, 24" (61 cm) polymeric lead wires.
- SPDT switch rated .17 A @ 120 VAC, .13 A @ 120 VDC on the AFS-141
- AFS-141 accuracy ±10% of set point, repeatability ±1%
- 1/2" female NPT ports; AFS-141 rated to 1000 psi (68 bar)
- AFS-141 temperature range -20 to 225°F (-29 to 107.2°C)
- Any mounting position; filtration of 50 microns or better recommended for the AFS-141
