Servo tank gauges are high-precision instruments used in the oil and gas industry for measuring liquid levels, interface levels, and density in storage tanks. They are essential for accurate inventory management, ensuring operational efficiency, and maintaining safety in refineries, terminals, and petrochemical plants.
Key Features of Servo Tank Gauges in the Oil & Gas Industry:
- High Accuracy Measurement – STGs offer precise level measurement with an accuracy of up to ±0.4 mm, making them ideal for custody transfer and inventory control.
- Multi-Parameter Monitoring – In addition to liquid level, STGs can measure interface levels (e.g., oil and water separation), density, and temperature.
- Continuous Real-Time Monitoring – Provides real-time data for process control, reducing risks of overfills and ensuring compliance with safety regulations.
- Integration with Inventory Management Systems – Compatible with digital communication protocols (Modbus, HART, Foundation Fieldbus) for seamless integration with SCADA and DCS systems.
- Suitable for Various Tank Types – Used in floating-roof tanks, fixed-roof tanks, and pressurized tanks storing crude oil, refined fuels, chemicals, and LPG/LNG.
- Reliable Operation in Harsh Conditions – Designed to withstand extreme temperatures, high-pressure environments, and hazardous areas with ATEX and IECEx certifications.
- Automatic Density Profiling – Helps in detecting stratification and changes in product composition inside the tank.
Popular Applications in the Oil & Gas Sector:
- Crude Oil Storage Terminals – Ensures precise measurement for custody transfer and regulatory compliance.
- Refineries & Petrochemical Plants – Used for process control and product blending.
- LNG & LPG Storage – Monitors cryogenic liquids with high accuracy.
- Pipeline & Distribution Facilities – Helps in tracking inventory and preventing losses.
