High Accuracy Tank Gauging for Bulk Liquid Storage Tanks
Get precise level, temperature and pressure measurements for inventory and custody transfer in large storage tanks.
High Performance Bulk Liquid Measurements for your Tank Farm
The Rosemount Tank Gauging System ensures accurate level, temperature, and pressure measurements for inventory control, oil movement and overfill prevention. The system is suitable for all tank types: pressurized or non-pressurized, with fixed or floating roofs. Applications include bulk liquid storage tanks in tank terminals, refineries, aviation fuel depots, full containment tanks for liquefied gases, petrochemical industries, distilleries, biofuel plants, vegetable oil depots, and many more. Thanks to state-of-the-art radar level measurement technology the system is highly accurate and reliable, and easy-to-use software improves inventory management in the control room as well as at other sites such as corporate HQ. Further benefits include:
- Certified custody transfer accuracy
- Compliance with safety standards such as API 2350 and IEC 61511
- Simplified automation and expansion with wireless solutions
- Emulation technology to easily replace old gauges from other vendors

The Rosemount 765 has an integrated water level sensor attached to the temperature sensor tube to measure free water level at the bottom of the tank. It enables correct product volume calculations.
Rosemount multiple spot temperature sensors measure temperature with a number of Pt-100 spot elements placed at different heights to provide a tank temperature profile and an average temperature.
Only fully immersed elements are used to determine product temperature. One of the temperature sensor elements may be installed inside the water level probe. Each sensor is connected to the Rosemount 2240S transmitter.
