Dwyer Instruments SFI-100-1 1/2 Indicator

Dwyer Instruments SFI-100-1 1/2 Indicator

For contractors monitoring standard fluid lines, the Dwyer Instruments SFI-100-1 1/2 Sight Flow Indicator provides a heavy-duty, visual verification solution for residential and industrial piping systems. This 1.5-inch NPT flow indicator is engineered with a robust bronze body and a single tempered glass window, allowing for immediate confirmation of flow movement without the need for additional instrumentation. The internal rotating impeller, constructed from UV-stabilized plastic, offers high-visibility motion even in low-light utility environments. Technical specifications support a maximum operating pressure of 125 psig and a temperature limit of 200°F, making it a reliable choice for hydraulic tanks, coolant lines, and pressure vessels. Its bidirectional design allows for both horizontal and vertical mounting orientation, provided the impeller remains unobstructed. The removable window assembly simplifies maintenance, enabling technicians to clean the interior or replace seals without removing the entire body from the line, ensuring long-term system integrity in liquid and gas applications.

Key Benefits
  • Enhanced Visual Diagnostics: The bright red impeller provides instant flow verification for system troubleshooting.
  • Rugged Material Construction: Durable bronze housing ensures corrosion resistance in demanding HVACR and hydraulic service.
  • High Temperature Capability: Rated for fluid temperatures up to 200 degrees, suitable for hot water and steam condensate monitoring.
  • Field Serviceability: Features a removable glass window for fast cleaning and gasket seat inspection.
  • Versatile Installation: Compatible with 1-1/2 inch female NPT threaded process connections for seamless integration into existing pipelines.
Common Questions

Can the SFI-100-1 1/2 be used with directional flow?
Yes, this model supports bidirectional flow; however, the impeller is most effective when the unit is mounted horizontally with the belly at the bottom to prevent air pocket interference.

What fluids are compatible with this sight flow indicator?
The unit is designed for compatible gases and liquids. The wetted materials include bronze, tempered glass, a 316 SS pin, and a Buna-N gasket.

Is the window glass replaceable if it becomes etched?
Yes, the tempered glass window can be unscrewed and replaced using a standard gasket kit, allowing for easy maintenance of visual clarity over time.
