Emerson Introduces Raptor - a Revolutionary New Tank Gauging System

November 15th 2010

Emerson has launched Raptor, a new fully scalable tank gauging system based on open technology. Easy to install the devices needed today as well as adding or replacing units tomorrow. Outstanding flexibility that will protect your investment for a long time. With Raptor, refineries and tank farms can easily become and stay efficient.

Unique safety and redundancy features

The Raptor system includes new safety technologies to help protect plant assets, the environment and human lives. One example is the unique 2-in-1 functionality—with two independent gauges in one single enclosure—providing SIL 3 safety for overfill prevention. There are also a number of other dual redundant configurations available to suit individual tank safety requirements.

New level of net volume accuracy

Raptor is built around a new line of 0.5 mm (0.02 in.) precision radar level gauges, plus ultra stable temperature transmitters with 3- or 4-wire multiple spot sensors. The result is the highest available precision in net volume calculations for custody transfer and inventory management. Equipment such as pressure and water bottom measurement sensors can also be added as well as operator interface software. Having access to reliable and accurate tank content information in real time is key to high plant efficiency, as the operators can handle even more tanks, fill the tanks higher and better utilize the storage capacity.

Large installation savings

Raptor reduces installation costs substantially. The unique bus-powered 2-wire Tankbus is based on self-configuring FOUNDATION fieldbus technology, allowing easy start-up and integration of all system units. 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.

There are many tank farms with gauging based on older technology, even in fairly recent installations, leading to maintenance problems and low performance. Raptor can emulate gauges from other manufacturers. This means the customers can add Raptor units to their existing system using the same cabling and control room infrastructure.

Wireless is an option

The Raptor system will include Emerson’s Smart Wireless functionality, eliminating the need for long distance signal wiring. This is especially valuable when no suitable ground cabling is available and it is necessary to cross roads, or when ground conditions make cabling expensive. Wireless communication can also be used as a redundant and independent communication path alongside traditional wired communication.

Global leader in high precision tank gauging

Emerson’s Rosemount Tank Gauging is the world market leader in systems for high precision tank gauging, used at refineries and bulk liquid storage plants. The systems are applied on all types of storage tanks, both fixed roof and floating roof tanks. The radar gauges use the drip-off antenna concept, proven in more than 100,000 installations worldwide. As a consequence, they can be used in virtually any liquid ranging from light products such as LPG, LNG and gasoline to crude oils and asphalt.
