| |
| Rosemount TankRadar Rex is a state-of-the-art inventory and custody transfer radar tank gauging system for storage tanks. It fulfills the highest requirements on performance and safety. The development of Rosemount TankRadar Rex is based on 25 years experience in radar level gauging. More than 50,000 radar gauges have been delivered by Rosemount. |
| |
 |
| The Rosemount TankRadar Rex System can be used at bulk liquid storage tanks at refineries, independent tank terminals, marketing terminals, pipeline terminals, petrochemical industry, liquified gas terminals, and aviation fuel deposits. |
| |
| The extensive range of TankRadar Rex 3900 Series level gauges fits all types of tanks, fixed or floating roofs, pressurized or non-pressurized. The Rosemount TankRadar Rex system measures the entire storage tank site. |
| |
| The system software can also make accurate measurement and calculation of liquid levels, temperature and water interface level, hydrostatic and vapour pressure, and observed density, and TOV, GOV, GSV and NSV. |
| |
| With a lean and clean installation, the Rosemount TankRadar Rex system offers also flexible field communication via many protocols eg, Profibus, Tiway, TRL/2. Intelligent gauge emulation compatible with all major tank gauging systems is also available. |
