2.3 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)
FOUNDATION™ 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-systems 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.
