Rosemount 5900S with Horn Antenna
Rosemount 5900S with horn antenna is a non-contact radar level gauge. It is designed for easy
installation on fixed roofs tanks, with smaller nozzles, down to 200 mm (8 in.).
■ Measures on a variety of products except asphalt or similar for which the parabolic antenna is
recommended
■ Custody transfer accuracy according to OIML R85:2008
■ Certified SIL 2 and SIL 3 capable according to IEC 61508
■ 2-in-1 functionality available for redundant level measurement
■ Communicates via a 2-wire, low voltage Tankbus for easy and safe installation
■ Installation normally with tank in service
Operating temperature in tank
Max. +180 °C (+356 °F)
Measuring range
0.8 to 20 m (2.6 to 65 ft) below flange.
Possibility to measure 0.5 to 30 m (1.6 to 100 ft). Accuracy may be reduced. For longer measuring range, consult your local
representative.
Pressure range
-0.2 to 2 bar (-2.9 to 29 psig)
Material exposed to tank atmosphere
Antenna and flange: Material corresponds to AISI 316/316L and EN 1.4401 /1.4404
Sealing: PTFE
O-ring: Viton®
Antenna dimension
175 mm (7 in.)
Nozzle diameter
Minimum 200 mm (8 in.)
Tank connection
The flange can be horizontal or 4° inclined for installation close to the tank wall.
The horizontal flange is used when highest accuracy and reliability is required. The 4° inclined version can be used to maintain high
accuracy when the gauge is installed close to the tank wall.

How it Works – TECHNOLOGY EXPLANATION The Rosemount 5900S uses FMCW technology, together with digital reference and filter technology for custody transfer accuracy. The radar gauge transmits microwaves towards the surface of the liquid. The microwave signal has a precise linear frequency variation around 10 GHz. The transmitted and reflected signals are compared. The frequency […]
