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.
