Dwyer Instruments SFI-100-1/2 Indicator
The Dwyer Instruments SFI-100-1/2 is a field-proven midwest sight flow indicator designed for immediate visual verification of fluid movement. Integrated with a 1/2" NPT female connection, this unit features a single window design with a high-visibility rotating impeller that provides clear confirmation of flow rates in both liquid and gas applications. Constructed with a heavy-duty bronze body and a tempered glass window, it is built to withstand the rigors of industrial hydraulic lines and coolant systems. This industrial flow indicator supports an operating pressure up to 125 psi (8.62 bar) and maintains a temperature limit of 200°F (93°C), making it a reliable choice for monitoring oil reservoirs and pressure vessels. For technicians installing in tight mechanical spaces, the SFI-100-1/2 supports both horizontal and vertical mounting, provided the "belly" is positioned correctly to prevent air pocket accumulation. Use a strap wrench and quality pipe sealant to ensure a leak-free seal on the threaded process connections.
Key Benefits- Rotating ABS impeller provides instant visual diagnostic of flow status, even in low-light mechanical rooms.
- Tempered glass window offers superior clarity and thermal resistance compared to standard plastic sight glasses.
- Bronze body construction ensures long-term corrosion resistance in HVACR and hydraulic fluid applications.
- Removable window design allows for straightforward internal cleaning and maintenance without removing the entire body from the line.
- Bi-directional mounting flexibility allows for seamless integration into existing 1/2" piping layouts.
Can the SFI-100-1/2 be used with steam?
No, this model is rated for a maximum temperature of 200°F and is intended for compatible gases and liquids. For steam applications, higher-rated specialty sight indicators are required.
What is the orientation requirement for vertical installation?
The unit can be mounted vertically with flow moving upward. For horizontal runs, ensure the "belly" of the housing is at the bottom to prevent entrapped air bubbles from obscuring the impeller.
Is the window replaceable if it becomes etched or clouded?
Yes, the tempered glass window is a serviceable part that can be unscrewed for cleaning or replacement, ensuring the indicator remains functional throughout the life of the system.
