2.4 System overview
The Rosemount Tank Gauging system is a state-of-the art inventory and custody transfer radar tank level
gauging system. It is developed for a wide range of applications at refineries, tank farms and fuel depots,
and fulfills the highest requirements on performance and safety.
The field devices on the tank communicate over the intrinsically safe Tankbus. The Tankbus is based on a
standardized fieldbus, the FISCO
(1)
F
OUNDATION
™ fieldbus, and allows integration of any device
supporting that protocol. By utilizing a bus powered 2-wire intrinsically safe fieldbus the power
consumption is minimized. The standardized fieldbus also enables integration of other vendors’
equipment on the tank.
The Rosemount Tank Gauging product portfolio includes a wide range of components to build small or
large customized tank gauging systems. The system includes various devices, such as radar level gauges,
temperature transmitters, and pressure transmitters for complete inventory control. Such systems are
easily expanded thanks to the modular design.
The Rosemount Tank Gauging system is a versatile system that is compatible with and can emulate all
major tank gauging systems. Moreover, the well-proven emulation capability enables step-by-step
modernization of a tank farm, from level gauges to control room solutions.
It is possible to replace old mechanical or servo gauges with modern Rosemount Tank Gauging devices,
without replacing the control system or field cabling. It is further possible to replace old HMI/SCADA-sys-
tems and field communication devices without replacing the old gauges.
There is a distributed intelligence in the various system units which continuously collect and process
measurement data and status information. When a request for information is received an immediate
response is sent with updated information.
The flexible Rosemount Tank Gauging system supports several combinations to achieve redundancy,
from control room to the different field devices. Redundant network configuration can be achieved at all
levels by doubling each unit and using multiple control room work stations.
