About SIGHT FLOW INDICATOR FLAPPER TYPE-SFI 120

Flapper Type Sight Flow Indicators are best suited transparent or slightly opaque solutions and are used for gases also. Position of the flapper indicates flow. One important use of these flow indicators is, in pipelines where a downstream value may remain closed and even through the flow indicator remains full, there may not be any flow. In such cases, the flapper position alone can indicate where there is flow.

Reliable Flow Observation for Industrial Applications

The SFI 120 Flapper Type Sight Flow Indicator provides clear, visual indication of media flow through robust, industrial-grade construction. Designed for straightforward inline installation in both horizontal and vertical orientations, it enables maintenance teams and operators to monitor liquids, gases, or oils in real-time, minimizing downtime and enhancing process safety. Its compatibility with ANSI, DIN, and JIS flanges ensures seamless integration into various systems.

Versatile Materials and Flexible Sizing

Offering body options including Cast Iron, Stainless Steel, or Bronze and flapper materials in SS304 or SS316, the SFI 120 accommodates site-specific requirements. With glass thickness up to 8 mm and sizes ranging from 15 mm to 300 mm nominal bore, it is suitable for a broad set of pipeline diameters, making it a flexible solution for diverse industrial environments.

FAQ's of SIGHT FLOW INDICATOR FLAPPER TYPE-SFI 120:

Q: How does the SFI 120 Sight Flow Indicator operate?

A: The SFI 120 uses a mechanical flapper inside a toughened borosilicate glass body that visibly moves when media flows through the pipeline, providing instant, visual confirmation of flow. It requires no external power source and is purely mechanical in function.

Q: What types of media can this flow indicator be used with?

A: This indicator is compatible with a variety of media, including liquids, water, gases, and oil, making it suitable for process, chemical, pharmaceutical, and utility pipelines.

Q: Where should the SFI 120 Sight Flow Indicator be installed?

A: It is designed for inline installation on pipelines, using either flanged (ANSI, DIN, JIS) or threaded connections. The indicator can be mounted both horizontally and vertically, depending on system requirements.

Q: When should I consider using a flapper type sight flow indicator?

A: Use a flapper type indicator when real-time visual inspection of flow is essential for process monitoring or maintenance, especially in industries where confirming the presence and direction of flow is critical.

Q: What is the process of installing this device?

A: Installation involves aligning the SFI 120 with the pipeline, bolting via flanged or threaded ends, and ensuring appropriate gasket sealing for leak-proof performance. No electrical connections are required, as the output is visual only.

Q: What are the benefits of using the SFI 120 in my system?

A: The primary benefits include robust construction for industrial reliability, straightforward maintenance, visual real-time flow verification, and enhanced operational safety by detecting flow presence or absence at a glance.
