Glass level guages

Glass Level Gauges – Overview

Glass level gauges are essential instrumentation devices used for visually monitoring liquid levels inside tanks, vessels, and pipelines across various industries. Offering clear, reliable, and real-time indication, these gauges provide operators with critical information to ensure safe and efficient process control.

Key Features and Design

• Durable Glass Tube or Sight Glass
  Made from high-quality borosilicate or tempered glass to withstand high pressure, temperature, and corrosive environments.

• Frame and Housing
  Typically constructed from carbon steel, stainless steel, or aluminum, with protective coatings to resist corrosion.

• Sealing and Connections
  Flanged, threaded, or welded ends for secure attachment to tanks or vessels, compliant with industry standards such as ANSI, DIN, and JIS.

• Optional Accessories

  • Protective covers and shields

  • Lighting kits for enhanced visibility

  • Valve assemblies for isolation and maintenance

  • Reflex or bi-color indicators for improved level reading

Typical Applications

• Oil & Gas Industry: Monitoring liquid levels in storage tanks, separators, and processing units.

• Chemical and Petrochemical Plants: Visual indication of corrosive or hazardous fluids.

• Power Generation: Boiler water level monitoring and feedwater tanks.

• Food & Beverage: Hygienic glass gauges for liquid ingredients and storage.

• Water Treatment: Control and safety of reservoirs and process tanks.

Advantages

• Immediate Visual Feedback: Provides clear and direct liquid level observation without instrumentation delay.

• High Reliability: Durable materials and robust construction ensure long-term operation in harsh conditions.

• Ease of Maintenance: Modular design with isolation valves enables quick cleaning or replacement without process interruption.

• Wide Range of Sizes and Pressure Ratings: Suitable for small vessels to large industrial tanks.

Glass level gauges are a trusted solution for operators needing straightforward, accurate liquid level monitoring. Their simplicity combined with rugged construction makes them indispensable across numerous industrial processes worldwide.
