Introduction: Visibility That Safeguards Process Integrity

In oil & gas facilities—whether a refinery, offshore platform, or chemical injection skid—level visibility is critical to process safety and reliability.

Tubular level gauges provide direct, real-time liquid level indication in storage tanks, separators, and hydraulic reservoirs—empowering operators to make fast, confident decisions in high-pressure environments.

“In oil & gas, what you can see, you can control—and tubular level gauges make visibility your strongest safety measure.”
— Rohit Menon, Senior Instrumentation Engineer, Petronash Engineering Services Pvt. Ltd.

Who Are the Top Tubular Level Gauge Manufacturers and Suppliers in India?

India’s leading OEMs—including Petronash Engineering—supply API-, ASME-, and ISO-certified tubular level gauges designed for superior accuracy, corrosion resistance, and long-term pressure integrity.

These gauges comply with global standards for liquid-level monitoring across the oil, gas, petrochemical, and power sectors.

The Role of Tubular Level Gauges in Oil & Gas Operations

A tubular level gauge offers a simple, reliable, and power-free method for directly observing fluid levels through a transparent glass tube connected to the process tank.

Applications:

• Wellhead Control Panels (WHCPs)
  
  

• Storage Tanks and Process Vessels
  
  

• Chemical Injection Skids and Condensate Tanks
  
  

• Utility and Hydraulic Systems
  
  

Fact: Direct-visual gauges remain preferred for remote installations due to zero power consumption and instant response (InstrumentationTools – Types of Level Gauges).

Why Indian Manufacturers Lead the Global Market

India has become a trusted hub for precision-engineered instrumentation. Local manufacturers, such as Petronash, produce API/ASME-compliant level gauges at globally competitive quality benchmarks.

Key Technical Highlights:

• Glass tubes rated up to 400 psi & 250°C
  
  

• SS316L / Duplex Steel housings for corrosion resistance
  
  

• Flange or socket-weld ends for easy installation
  
  

• Ball check valves for automatic shutoff on glass breakage
  
  

• Optional insulation, color scales, and chemical service variants
  
  

Value: Indian-made tubular gauges are exported to 70+ countries and meet ASME Section VIII and PED 2014/68/EU compliance standards.
