Introduction: Visibility That Safeguards Process Integrity
In every oil & gas facility - whether a refinery, offshore platform, or chemical injection skid - level visibility is the foundation of safe and reliable operations.
Tubular level gauges play a vital role in providing direct liquid level indication for storage tanks, separators, and hydraulic reservoirs, allowing operators to make quick, confident decisions.
“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?
Leading suppliers - including Petronash Engineering and partner OEMs - provide API-, ASME-, and ISO-certified tubular level gauges designed for accuracy, corrosion resistance, and pressure integrity. These gauges meet global standards for safe liquid-level monitoring in oil, gas, and chemical industries.
The Role of Tubular Level Gauges in Oil & Gas Operations
A tubular level gauge provides a simple yet highly reliable way to observe liquid levels directly through a transparent glass tube connected to the tank.
- Wellhead control panels and separators
- Storage tanks and process vessels
- Chemical injection skids and condensate tanks
- Utility and hydraulic systems
Reference: InstrumentationTools - Types of Level Gauges Fact: Direct-visual gauges remain preferred for their simplicity, zero power consumption, and immediate response - critical in remote field installations.
Why Indian Manufacturers Lead the Global Market
India has emerged as a global hub for precision-engineered instrumentation equipment, offering API- and ASME-compliant level gauges at competitive quality benchmarks.
- Glass tubes rated up to 400 psi & 250°C
- SS316L / Duplex steel housings for high corrosion resistance
- Flange or socket-weld ends for easy installation
