Rosemount 5900S Custody-Transfer Radar Level Gauge

Rosemount1 configuration

Configure Your Rosemount 5900S Radar Level Gauge

Premium tank-gauging radar level gauge — ±0.5 mm instrument accuracy. Custody-transfer accuracy per OIML R85:2008. SIL 2 / SIL 3 capable per IEC 61508. 2-in-1 redundancy option for two independent radar electronics per gauge. 10 GHz FMCW radar via 2-wire FOUNDATION Fieldbus Tankbus. Four antenna variants for different tank conditions: parabolic (1P, premium for fixed-roof without still-pipe, tolerant to product buildup and condensation), horn (1H, smaller fixed-roof nozzles down to 200 mm), still-pipe array (1A, for floating-roof crude/gasoline/product tanks with rust/deposit tolerance via Low Loss mode), and LPG/LNG (G1/G2/G4, for pressurized or cryogenic liquefied gas with integrated ball valve and optional built-in pressure sensor for vapor compensation). Pairs with the Rosemount 2410 Tank Hub for full custody-transfer chain and the Rosemount 2240S for temperature + density.
