OPTIWAVE 1010: NEW RADAR
OPTIWAVE 1010: NEW RADAR LEVEL TRANSMITTER FOR BYPASS CHAMBERS AND MAGNETIC LEVEL INDICATORS • 2-wire FMCW radar level transmitter for bypass chambers and magnetic level indicators (MLI) • Continuous measurement of liquids, no minimum dielectric constant when used with a float OPTIWAVE 1010 FMCW radar level transmitter for bypass chambers and magnetic level indicators (MLI) • Direct and accurate measurement of level in bypass chamber • Dual process seal system for maximum safety and removal of converter under process conditions Duisburg, January 19, 2016: With OPTIWAVE 1010, KROHNE introduces a new radar level transmitter for bypass chambers and magnetic level indicators . The 2-wire FMCW radar level transmitter is designed as a costeffective solution for the continuous level measurement of liquids in bypass applications in various industries, e.g. chemical, power, water and wastewater, or automotive. OPTIWAVE 1010 can be combined with the KROHNE BM 26 ADVANCED bypass chambers and magnetic level indicators (MLI), thereby adding a 4…20mA HART output to the mechanical devices. The combinations can be conveniently ordered as a whole, e.g. as BM 26 W1010 (OPTIWAVE 1010 welded to BM 26 ADVANCED). Alternatively, it can be welded on any bypass chamber with internal diameter 38…56 mm / 1.5…2.2”. Thus it is also an ideal solution for other MLI manufacturers to add a level radar measurement option to their product range. OPTIWAVE 1010 is competitively priced to replace reed chains, magnetostrictive and simple TDR transmitters that are typically used with bypass chambers or MLIs. In addition to a measuring accuracy of ± 5 mm / 0.2”, the FMCW principle offers a much better overall accuracy in bypass applications: while reed chain and magnetostrictive principles are measuring the float position which depends on the product density, the FMCW radar directly measures the liquid surface. Application range for OPTIWAVE 1010 includes almost any liquids with process temperatures ≤ +150°C / +302°F up to 40 barg / 580 psig and measuring ranges up to 8 m / 26.2 ft. With clean liquids of dielectric constant ε r ≥ 3 the device measures the surface directly, for ε r < 3, a float with target is used. OPTIWAVE 1010 features a dual process seal system that allows for removal of the converter under process conditions. The 2-wire loop-powered HART device is pre-configured in the factory and is delivered ready to use. Application-specific adjustments are possible via HART/ DD and DTM.

SIEMENS’ AERODERIVATIVE GAS TURBINE PASSED WITH THE HIGHEST MARKS FOR LNG It’s been said that turbomachinery is at the heart of every liquefied natural gas (LNG) plant, whether it’s large, mid-sized, or small. No matter what equipment is chosen, the ultimate goal is to optimize the economic return. The total expected lifecycle costs, including both operating expenses (OPEX) and capital expenditures (CAPEX), play a critical role when choosing turbomachinery for an LNG facility. Among the industrial gas turbines that the Dresser-Rand business offers is the SGT-A65 TR (Industrial Trent 60) aeroderivative gas turbine. This turbine has been selected by several operators and developers for their LNG projects thanks to its high efficiency, light weight, and speed range variation available from the free power turbine. The SGT-A65 TR has established a new benchmark for power output, fuel economy, and cost savings. The turbine is highly flexible, offering high power and efficiency with minimal drop-off at part load and reduced speed conditions. It has proven itself in many different environments including desert, arctic, tropical, and coastal and in different applications. More than 100 units have been sold with more than 1.1 million equivalent operating hours (EOH). The fleet leader has accumulated more than 110,000 EOHs. Last year Siemens and the Dresser- Rand business conducted a successful demonstration test of the SGT-A65 TR’s torque capability for mechanical drive applications. Breakaway and transient torque is vitally important in LNG projects, where it’s necessary to start the turbine driver while the compression train is fully pressurized. Single-shaft heavy-duty gas turbines were traditionally used in the past for these applications. They need starter-helper motors to produce the required breakaway torque at low speeds, and at the same time they also require decompression of the refrigerant loop to reduce the starting torque. It’s a complex process that can result in the loss of expensive refrigerant, environmental issues, and additional costs. On top of that, the starter-helper motors and support add complexity and costs to the overall project. With the torque capability now proven, these requirements can be mitigated, making the financial and technical aspects simpler for customers. Thanks to the three-shaft architecture of the SGT-A65 TR engine, the torque capability proved to be even better than expected. The tests show that there are no concerns about full pressure restart torque for the project. With the acquisitions of Dresser-Rand and Rolls Royce Energy’s gas turbine product line, Siemens has significantly boosted its resources and reputation as a global player in the oil and gas industry by expanding its product and services portfolio. Siemens’ design for LNG projects secures the best total cost of ownership and maximizes uptime to keep production flowing. With the largest service network in the industry, Siemens can help maximize uptime and operational reliability. And the company can optimally leverage the power of digitalization to provide customers with better decision-making capabilities by turning data into useful, real-time information. LNG customers can select the most suitable solution for their projects, whether they need applications for industrial or aeroderivative gas turbine-driven compression, or all-electric LNG and gas-to-power applications in remote areas. Siemens’ highly efficient products help reduce operating costs over the lifecycle of the equipment.
