The Rosemount 5900S is a high-accuracy radar level gauge designed for automatic tank gauging and bulk liquid inventory management. Its radar measurement technology provides reliable level data for storage operations and custody transfer applications. When combined with compatible multi-spot temperature sensors, it can support accurate net volume calculations in accordance with applicable API standards.
The 5900S is available in standard and 2-in-1 versions. The 2-in-1 configuration integrates two independent radar units in one housing, enabling redundant level measurement or separate level and overfill safety measurement through a single tank opening.
Key Features
- ±0.5 mm instrument accuracy under reference conditions
- Custody transfer measurement for precise bulk liquid inventory management
- SIL 2/SIL 3 certification according to IEC 61508, depending on configuration
- 2-in-1 radar option for independent level and overfill measurement
- Two-wire intrinsically safe Tankbus power supply
- Compatible with wired and/or wireless tank gauging system architectures
- Supports integration with multi-spot temperature sensors for net volume calculations
Suitable Applications
- Crude oil storage tanks
- Refined petroleum product tanks
- Liquefied gas storage
- Bitumen storage
- Bulk liquid terminals
- Custody transfer and inventory management
- Tank overfill prevention systems
Technical Highlights & Selection Considerations
- Measurement accuracy: ±0.5 mm under specified reference conditions; overall system accuracy depends on the complete installation and operating conditions.
- Safety configuration: Select the standard or 2-in-1 version according to level measurement, redundancy, and overfill protection requirements.
- Tank compatibility: Confirm the tank type, antenna selection, installation arrangement, and measurement range before ordering.
- System integration: Verify compatibility with the existing Rosemount Tank Gauging system, Tankbus equipment, and control system.
- Volume calculations: Multi-spot temperature sensors and other required system components may be needed for accurate net volume calculations.
- Standards and approvals: Confirm the required custody transfer approvals and safety certifications for the exact model and configuration.
Frequently Asked Questions
Q1: What is the accuracy of the Rosemount 5900S?
