Durable Construction for Diverse Applications

Made with corrosion-resistant metals and high-quality glasses, the Sight Flow Indicator withstands aggressive chemicals, steam, oil, or water, making it suitable for industries like petrochemical, food & beverage, water treatment, and power plants. The device is engineered for 0C to 150C temperatures and pressures up to 20 bar, ensuring safe and long-term operation.

Flexible Configuration & Easy Installation

Users benefit from several material and connection optionsflanged, threaded, or socket weldallowing seamless integration into existing pipelines ranging from 1/2 inch to 6 inches in diameter. The sight flow indicator accommodates both gasket and O-ring sealing, and supports both horizontal and vertical installation, offering exceptional versatility.

Reliable Visual Flow Monitoring

The full view or double window design, paired with borosilicate or toughened glass, provides a clear, wide-angle view of the medium. This enables prompt identification of flow presence, direction, color, clarity, and contaminants for liquids and gases, which is crucial for quality control and system safety.

FAQs of Sight Flow Indicator:

Q: How is the sight flow indicator installed in a pipeline?

A: The sight flow indicator is installed inline using either flanged, threaded, or socket weld connections as per pipeline specifications. It can be mounted horizontally or vertically, providing flexibility for various pipeline layouts.

Q: What are the typical applications of this sight flow indicator?

A: This device is widely used for visual observation of flow in industries such as chemical processing, pharmaceuticals, food and beverage, petrochemicals, power plants, and water treatment facilities.

Q: When should I choose borosilicate glass over toughened glass for the window?

A: Borosilicate glass is ideal for high-pressure, thermal shock, and chemically aggressive environments, while toughened glass is preferable where mechanical strength is prioritized or impact resistance is needed. Selection depends on your process requirements.

Q: Where can this indicator be used with respect to temperature and pressure limits?

A: The sight flow indicator is suitable for processes operating between 0C to 150C and pressures up to 20 bar, making it versatile for a range of industrial environments.

Q: What is the benefit of 360-degree viewing in this device?

A: The 360-degree viewing feature allows operators to monitor flow from multiple angles, facilitating quick inspection of fluid clarity, color, and the presence of contaminants, improving operational reliability and safety.

Q: How does the sealing type (gasket or O-ring) affect operation?

A: Both gasket and O-ring seals ensure a leakproof operation. The choice depends on the media and operating conditionsO-rings are preferred for higher sealing efficiency, while gaskets are common for general-purpose applications.

Q: What is the process for maintaining the sight flow indicator?

A: Routine maintenance includes checking seal integrity, cleaning the glass window for visibility, and ensuring the bodys anti-corrosive coating remains intact. The clear and accessible construction enables straightforward maintenance, supporting long service life.
