Rosemount 5900S Radar Level Gauge

The Rosemount 5900S Radar Level Gauge delivers ±0.5 mm (0.020 in.) instrument accuracy, reducing level measurement uncertainty to a minimum. It enhances your storage operation by providing certified custody transfer accuracy, better inventory management and reliable loss control data.
The Rosemount 5900S is normally combined with high precision multi-spot temperature sensors for highest accuracy API standard net volume calculations.
The Rosemount 5900S takes overfill safety to a higher level with an innovative 2-in-1 feature which includes two radar gauges in one housing for independent level and overfill measurement. It is SIL 2 and SIL 3 certified according to IEC 61508 and enables API 2350 compliant solutions.

Accuracy: ± 0.5 mm (± 0.020 in.)
Stability: Typically < ± 0.5 mm (0.020 in.) in -40 to +70 °C (-40 to +158 °F)
Update Rate: New measurement every 0.3 second
Communication Protocol: Foundation Fieldbus for connection to Rosemount 2410 with self-configuring Tankbus or any Foundation Fieldbus host system. A Rosemount 5900 level gauge in combination with a 2410 Tank Hub enables wireless communication and emulation of gauges from other manufacturers.
Custody Transfer Approval: OIML R85:2008, and national certifications such as PTB, NMi etc.
Safety: SIL 2 and SIL 3 certified. TÜV tested and WHG approved for overfill prevention.
Metrology Sealing: Yes
Emulation Capability: Possible to integrate with legacy tank gauging systems. Supports emulation of other vendors’ communication protocols: E.g. Enraf, L&J Tankway, Varec Mark/Space, Whessoe, GPE, Sakura and Tokyo Keiso.
Power Supply: FISCO: 9.0 – 17.5 VDC polarity insensitive (for example from 2410 Tank Hub). Entity: 9.0 – 30.0 VDC polarity insensitive.
Ambient Temperature: -40 to +70 °C (-40 to +158 °F). Minimum start-up temperature is -50 °C (-58 °F).
Antenna Type: Parabolic antenna, still-pipe array antenna, horn antenna, LPG/LNG antenna.
