Rosemount™ 5900C Radar Level Gauge
The Rosemount 5900C Radar Level Gauge provides ± 1mm (0.
04 in.) instrument accuracy. It is normally combined with high precision multiple spot temperature sensors for net volume calculations. It is SIL 2 certified according to IEC 61508.
Rosemount™ 5900C Radar Level Gauge


± 1mm (0.04 in.), ± 2mm (0.08 in.)
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.
