Rosemount 5900C Compact Radar Level Gauge

Rosemount1 configuration

Configure Your Rosemount 5900C Radar Level Gauge

Cost-optimized version of the Rosemount 5900S tank-gauging radar — ±1 mm or ±2 mm instrument accuracy (vs 5900S's ±0.5 mm Premium) in a simpler chassis. SIL 2 capable per IEC 61508 (no SIL 3 like the 5900S). Single-electronics only (no 2-in-1 redundancy). 10 GHz FMCW radar via 2-wire FOUNDATION Fieldbus Tankbus. Five antenna variants for different tank conditions: parabolic (1P), cone (1C, smaller-nozzle alternative to the 5900S horn), still-pipe array (1A), LPG/LNG (G1/G2, no G4), and 1/2-inch still-pipe (smallest pipe diameters). Custody transfer support limited (most variants are code 0 only). Pairs with the Rosemount 2240S for temperature; common in smaller tank farms and distribution terminals where the 5900S premium accuracy would be over-spec.

5900C Compact Radar Level Gauge

Compact version of the Rosemount 5900S tank-gauging radar — ±1 mm accuracy (slightly looser than the 5900S's ±0.5 mm) in a smaller, lower-cost form factor. SIL 2 certified, custody-transfer capable. Used in smaller tank farms, distribution terminals, and inventory-management applications where the 5900S would be over-spec. Same Tankbus FOUNDATION Fieldbus output. Pairs with the Rosemount 2240S for full level + temperature tank-gauging.
