Servo Tank Gauges Integrated with Radar and Pressure Transmitters

In industries where liquid level measurement accuracy is critical—such as oil & gas, petrochemicals, and bulk liquid storage—advanced tank gauging technologies are essential for inventory control, custody transfer, and safety compliance. Among these, servo tank gauges (STGs) stand out for their precision and reliability. When integrated with radar level transmitters and pressure sensors, servo tank gauges offer a comprehensive and redundant tank monitoring solution that enhances operational efficiency and data confidence.

Why Integrate with Radar and Pressure Transmitters?

While servo gauges are highly accurate, integrating radar and pressure transmitters provides key advantages:

1. Redundancy and Cross-Validation

Radar transmitters use non-contact microwave technology to measure liquid level. Combined with servo readings, this creates a dual-source verification system to eliminate measurement discrepancies and reduce the risk of error.

2. Full Tank Profile Data

Radar: Provides continuous surface level monitoring.

Servo: Offers point-specific interface detection and spot temperature/density.

Pressure sensors (hydrostatic): Deliver reference bottom pressure, supporting volume and mass calculations.
Together, they create a complete vertical profile of the tank contents.

3. Improved Safety and Compliance

Critical for custody transfer and legal metrology, this integrated system supports compliance with API, ISO, OIML, and MID standards, and helps detect issues like tank leaks, overfills, or stratification in real time.

4. Reliable Performance in Harsh Conditions

Radar works well with volatile or vapor-filled tanks.

Servo gauges perform reliably with interface layers or high-viscosity products.

Pressure transmitters remain effective even with non-homogeneous fluids.
The combination ensures consistent performance in challenging environments.

Servo tank gauges integrated with radar and pressure transmitters represent a new standard in tank gauging systems—offering unmatched accuracy, safety, and system flexibility. By combining the strengths of each technology, facility operators gain a powerful toolset for inventory management, compliance assurance, and operational excellence.
