Inventory Measurement Solutions for Full Containment Storage Tanks
Solve your cryogenic measurement challenges with a complete and integrated system solution.
Manage Inventory Safely, Accurately and Reliably
When storing liquefied gases such as LNG, accurate and reliable measurements are critical. Radar technology provides a robust and virtually maintenance-free level solution, complete with remote proof-testing capabilities and voted overfill prevention. The simplified system infrastructure provides cool-down temperature control, stratification - and leak detection as well as rollover prediction - all of which can be visualized in one software.

Rosemount TankMaster is a powerful, easy-to-use Windows-based inventory management software package. Rosemount TankMaster collects real-time tank gauging data such as level, temperature, water interface level and pressure. It automatically calculates volume and mass for inventory and custody transfer for bulk liquid storage tanks. It also provides operator overview, configuration, setup and service for Rosemount tank gauging systems.
- Increase plant efficiency by getting a complete tank overview.
- Get real time inventory calculations with API standard net volumes.
- Achieve network interoperability with host systems and other vendors.
Tank Gauging
