Tank-Gauging System Helps Refineries Handle Increasing Demands

Emerson Process Management's new Raptor tank-gauging system consists of a complete range of tank gauging instrumentation including high performance, non-contact radar level gauges, temperature and pressure transmitters and water interface sensors and inventory management software. Tank hubs are used to communicate with the measuring instruments and control room via standard communication protocols. The design is based on open technology and is fully scalable with functionality and scope that can be adapted to any application and performance class. 

The system includes new safety technologies to help protect plant assets, personnel and the environment. One example is the unique two-in-one functionality with two independent radar gauges in one single enclosure to provide SIL 3 safety for overfill prevention. There is also a number of other dual redundant configurations available to suit individual tank safety requirements.

Raptor's bus-powered two-wire Tankbus communication is based on self-configuring Foundation fieldbus technology. The tank units are intrinsically safe, which means no expensive cable conduits are required. Communication to the control room can be made using Modbus over most existing cabling, or using other fieldbus standards.
