Reliability and accuracy for level measurement
The Rosemount 5600 Series is a powerful, noncontact radar level measurement transmitter for process applications, on liquids and slurries.
Diaphragm seals match pressure transmitter
Fisher-Rosemount have invested in the design and development of a complete range of Diaphragm Seal Solutions, specifically to match the high specification 3051 transmitter.
Duplicated temperature monitoring in single unit

It also coats anything it touches, and so level measurement in the 12m-high tanks - in the presence of heating coils, agitator paddles and fill tubes - has been a challenge for simple radar gauges, with many false echoes from these obstructions.
The advanced signal processing technology used in the Rosemount 5600 software enables reliable surface measurement in such difficult applications.
Automatically the software collects and analyses data on the echoes received throughout the tank operating range.
This data is used to define the position and size of the "false echoes" from the tank obstructions - echoes that would be registered as a surface reflection using a conventional radar gauge.
The operator uses this data in the Rosemount Radar Master Configuration software to set a profile for the surface level detection threshold, so that echoes from resin build-up on tank obstructions are ignored.
Further, the Rosemount 5600 uses intelligent echo tracking to monitor the progressive movement of the surface level position, applying the logic that the surface movement is relatively slow, most of the time.
The Rosemount Radar Master Configuration software, installed on a laptop, enables remote access of the Rosemount 5600 transmitter using Hart digital communications - an important feature when the tank roof is relatively inaccessible, and heated to 70C.
From the comfort of the control room a complete view of the tank radar echo profile is available at any time, with the associated threshold levels and echo tracking logic settings used for surface echo detection.
Rosemount 5600 radar gauges have successfully monitored this hot, turbulent level measurement application in phenolic resin tanks, and achieved the reputation for reliability that the name Radar Master implies.
