OVERVIEW
Rosemount Raptor is a revolutionary, 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 Rosemount Raptor 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.
Rosemount Raptor 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 Raptor 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
continously collect and process measurement data and status information.
When a request for information is received an immediate response is sent
with updated information.
The field devices on the tank communicate over the intrinsically safe
Rosemount Raptor Tankbus. The Tankbus is based on a standardized
fieldbus, the FISCO

™ fieldbus, and allows integration of any
device supporting that protocol. By utilizing a 2-wire field bus the power
consumtion is minimized. The standardized field bus also enables integration
of other vendors’ equipment on the tank.
The flexible Rosemount Raptor system supports several combinations to
achieve redundancy, from control room to the different field devices.
Redundant network configuration can be achived at all levels by doubling
each unit and using multiple control room work stations.
