The Industrial Applications of Sight Glass Flow Indicators

Sight glass flow indicators can be utilized in any industry where a quick check of the flow of fluids or gases in the pipeline is beneficial. You can use them for:

  • Process Control: Use them to monitor and control processes in multiple industries, from chemical manufacturing to power generation.
  • Troubleshooting: Operators can use sight glass flow indicators to identify issues such as blockages, air bubbles, or irregular flow patterns within the system.
  • Safety Checks: By visually inspecting the flow, you can detect any abnormalities that may indicate potential problems or unsafe conditions.

Additionally, sight glass flow indicators do not require penetration into the system, thereby minimizing the risk of leaks or contamination. Plus, you can install them into existing pipelines without making significant modifications to the system. At Hawleys, we stock:

Bronze Sight Glasses

Bronze sight glass flow indicators offer a diverse range of applications. The alloy's corrosion resistance ensures longevity, maintaining the integrity of the indicator over time, even in environments with moisture or aggressive substances. 

The inherent strength and durability of bronze makes it suitable for applications exposed to physical stress or pressure. The material's high temperature resistance allows for reliable performance in elevated temperature settings. These sight glasses provide a versatile solution compatible with various fluids and their machinability enables intricate designs. 

Ductile Iron Sight Glasses

Ductile iron sight glasses are another robust solution for many industrial applications. Crafted from a ductile iron alloy, they boast enhanced strength and toughness, ensuring resistance to mechanical stresses and impacts. 

The sight glasses are corrosion-resistant and the material's ductility allows for significant deformation without breakage. Ductile iron's ability to withstand a range of temperatures makes these sight glasses versatile for applications encountering varying thermal conditions.

Note: As with any sight glass flow indicator, proper consideration of the material's compatibility with the fluid and environmental conditions is essential.
