Section 2. Overview
2.3 SYSTEM 
OVERVIEW
Raptor 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

™ 
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 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.
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 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 
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 Raptor 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.
