The system is based on open technology and is fully scalable, making it easy to install the specific devices needed today and to add or replace units in future. With Raptor, refineries and tank farms can easily become and stay efficient. 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 0.5mm (0.02 inch) 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 utilise the storage capacity. Large installation savings Raptor reduces installation costs substantially. The unique bus-powered 2-wire Tankbus is based on self- configuring FOUNDATIONTM 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, which eliminates 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.

DIMPLEFLO HEAT EXCHANGERS SAVE ENERGY In the face of ever-increasing energy costs, many manufacturers and service providers are utilising Australian-made Dimpleflo Modular Heat Exchangers to recover energy from any warm or hot product or effluent. Hot sludge or wastewater is passed through the inner dimpled surface of the Dimpleflo, cooling from 60°C to 30°C, while boiler feed water is preheated in the jacket of the Heat Exchanger from 20°C to 50°C. This significant energy recovery can be used wherever a hot product or waste is cooled. The beauty of the Dimpleflo system is that it is maintenance free, even when hot waste products include large chunks, particles or sludge. Some of the features of 'Dimpleflo' and 'Dimplestream' tubular heat exchangers include: • Designed and manufactured in Australia. • Flexibility in heat transfer design to meet specific dimensional or functional requirements. • Unique Dimple-profiled Monotube enables a self-draining, high efficiency heat exchanger that is virtually unblockable. • Dimple profile promotes a highly turbulent flow and maximises heat transfer coefficients. • Can be constructed using corrosion- resistant alloys such as 2205 Duplex and Titanium. • Short lead times. • Requires minimal maintenance.

KSB AXIALLY SPLIT CASE WATER PUMPS When KSB designed their new RDLO range of axially split case water pumps, many years of experience were taken into consideration across different aspects of clients' needs, including high efficiency, performance range, low NPSH requirements and the benefits of ease of maintenance. Many of the features are an extension from the smaller Omega series. The RDLO series is one of the newest designs available on the market, with hydraulic efficiencies up to 91 per cent at BEP, utilising double volute casings and three different impeller profiles in most sizes for optimum selection and hydraulic stability. Easier maintenance was a major design factor, with features including various material options on all components, casing and impeller wear rings, a dry sealed shaft arrangement with a short bearing span, all secured with one simple outboard locknut (enabling right and left hand drive with common components), The Raptor system includes the ultra-precise Rosemount 5900S radar level gauge. The Dimpleflo Modular Heat Exchanger.
