Description

The Rosemount 5900C Radar Level Gauge sets the standard for bulk liquid storage tank monitoring in terminals, chemical storage facilities, and refineries. Operating on 10 GHz Frequency Modulated Continuous Wave (FMCW) radar technology, the gauge delivers continuous surface measurements through atmospheric turbulence, volatile vapors, and foaming media.

Industrial Tank Gauging with the Rosemount 5900C Radar Level Gauge

Bulk liquid inventory management demands uncompromised stability across wide temperature extremes. The Rosemount 5900C Radar Level Gauge eliminates moving components, mechanical tape friction, and float degradation found in traditional tank gauges. When combined with multi-spot temperature elements and hydrostatic pressure transmitters, the gauge delivers accurate net volume calculations for loss control accounting.

Industrial Tank Gauging with the Rosemount 5900C Radar Level GaugeCertified Functional Safety and Overfill Prevention

Tank overfill protection is critical for facility security and regulatory compliance. The Rosemount 5900C Radar Level Gauge is certified SIL 2 capable according to IEC 61508 and supports API 2350 compliant safety architectures. Plant operators can carry out routine safety proof-testing remotely without opening tank hatches, eliminating personal exposure to hazardous terminal vapors.

Flexible Installation and Antenna Options

Process facilities benefit from lower installation costs because most antennas mount directly while tanks remain in live operation. The Rosemount 5900C Radar Level Gauge supports horn antennas, parabolic dish designs, and still-pipe arrays suited for crude oil, bitumen, chemical solvents, and clean fuels. Utilizing a 2-wire intrinsically safe Tankbus, the gauge integrates smoothly into both hardwired infrastructure and Emerson Smart Wireless networks.
