Section 2. Overview
2.3 SYSTEM
OVERVIEW
The Rosemount Tank Gauging state-of-the art inventory and custody transfer
radar tank level gauging system 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 versatile Rosemount Tank Gauging system 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 gauges, 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.
