What Exactly Is A Flange Sight Flow Indicator?

flange sight flow indicator

A Sight Flow Indicator is a reliable and easy-to-use device that allows operators to monitor fuel flow in pipelines. The assembly is composed of a metal body with a viewing window or openings, gaskets, and a mounting connection, such as a flanged, threaded, or sanitary clamp connection.   Industrial applications often use flanged sight flow indicators between API valves and tanker piping for real-time visual feedback on fuel flow. This ensures accurate, consistent, and safe fuel flow for all your applications.

What Is the Function of a Flanged Sight Flow Indicator?

A flanged sight flow indicator provides a window to observe the process within a pipeline safely and clearly. By allowing the operator to view how the process liquid moves through the channel, any irregularities that might be present can be easily identified. The flanged mounting option is suitable for various industrial applications and ensures maximum safety and accuracy.

What are the Types of Flanged Sight Flow Indicators?

There are countless sight flow indicators available to monitor various processing systems. In certain applications, you may require a full-view indicator for maximum visibility or a more rugged option for harsher processing conditions. Our flange-mounted sight flow indicators are designed to meet requirements and provide reliable performance in any environment. With a wide selection of styles and sizes, you can be sure to find the right indicator for your application and its specific processing criteria.

How to Choose the Best Flanged Sight Flow Indicator?

Choosing the perfect flanged sight flow indicator for your application can be daunting. However, with our comprehensive online guide, you can easily select the correct type of indication for your application and tailor it to the proper flange mount. Our guide walks you through all the steps and considerations necessary to make the best choice for your needs. With this knowledge, you can ensure you have the perfect flanged sight flow indicator for your application.

  • View Through vs. Full View

The view-through flow indicator has two windows allowing an operator to see the fluid flow illuminated from behind. This design is ideal for ANSI pressure classes, high temperatures, and harsh fluid applications, offering superior visibility and reliability. The indicator also features a unique design for maximum durability and accuracy, even in the most demanding environments.

The 360 view is the ideal solution for observing process fluid for clarity, color, foam, and other conditions and detecting moisture. However, depending on the model, it may be suitable for high temperatures and pressures, or it may not. Therefore, additional measures must be taken for applications in these extreme conditions to ensure accuracy and safety.

  • Type of Indication

Rotary, flapper, flutter, ball, or drip Indicators are invaluable tools for quickly and accurately gauging the direction and speed of flow of process materials.   These indicators are especially useful for measuring colorless gases and opaque fluids, as they visually represent the flow. With these indicators, you can quickly identify changes in the flow rate, direction, and speed of the material, allowing you to adjust or control the process as needed.

  • Carbon Steel vs. Stainless Steel

Carbon steel is a strong and durable material widely used in industrial applications due to its low cost and superior strength. On the other hand, stainless steel provides excellent corrosion resistance, essential in many applications, such as pharmaceuticals, food, and beverage production. When deciding between these two options, be sure to consider the environment you’ll be using them in, as well as the specific needs of your project.

  • Gaskets

Gaskets are critical in ensuring that your sight flow indicator performs to its full potential. When selecting a gasket for your sight flow indicator, be sure to consider the compatibility of the gasket material with your process media and temperature requirements. With a wide variety of gaskets available, you can be sure to find the perfect fit for your needs.

  • Type of Glass

Borosilicate glass is ideal for areas where hot equipment may be exposed to frequent washdowns with cold water or corrosive chemicals. Its superior thermal shock and caustic resistance make it much more durable than soda lime glass, making it the safest option for protecting your equipment. When protecting your equipment from extreme temperatures and corrosive chemicals, you can count on borosilicate glass to stand up to the challenge.

Quartz or sapphire glass is the recommended material for applications that require protection from high temperatures, such as those greater than 500◦ F. Such applications can include high-temperature steam environments, where quartz or sapphire glass can provide superior protection compared to other materials.
