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
(2)
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-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.
