First Guided Wave Radar Level Transmitters to be Certified for IEC 61508 SIL2/3 Applications
K-Tek (USA), a member of the ABB Group, have announced that the company's MT5000 Series of Guided Wave Radar Transmitters has been certified for use in SIL2/3 (Safety Integrity Levels 2 and 3) applications. The MT5000 Series is the only guided wave radar transmitter in the industry to be certified to the demanding, performance-based IEC 61508 safety standard. To obtain SIL
certification, the products must be analysed based on quantitative data and tests indicating the length of time between failures and expected performance in the field. This certification emphasises quantitative measures for reducing risk at the process measurement level when implementing Safety Instrumented Systems (SIS) in process plant environments.
"When it has to be safe and reliable, you want a device that has been thoroughly inspected and certified by a third party," said Charles Richard, Global Product Manager for Radar products at K-Tek. "K-Tek is the only guided wave radar transmitter manufacturer to provide a certified SIL2/3 product offering. The MT5000 Series provides reliable measurements even in the most complex situations. This makes it ideal for a variety of level applications, such as light hydrocarbons, low dielectric fluids, or fluids with foamy surfaces. Additionally, the MT5000 is self-monitoring, continually looking for any faults that could cause device failures or false indications."
The MT5000 devices feature an integrated graphic display for quick and easy viewing of waveform screens. The user-friendly setup menu supports a wide range of languages for fast setup in virtually any region of the world. A concentric waveguide directs the radar beam, alleviating divergence problems and echoes from tank walls and surrounding structures. In addition, the devices are unaffected by variations in specific gravity, and accurate level measurements are provided even with widely varying temperatures and pressures: up to 5000 psi (344 bar) or 800o provides a strong signal over distances.

The 1520 from SOR (USA) is a vertically mounted, vane-operated flow switch suitable for plant and OEM applications where open or closed contacts are required to signal flow or no flow conditions. The vane extension arm moves a magnet that actuates (deactuates) a hermetically sealed reed switch.
The 1520 belongs to the 1500 series for the oil and gas industry. Low cost and all stainless steel construction sets this product apart from others.
“Besides its rugged construction and that it is CSA explosion proof certified,” says SOR product manager, Michael Lian, “the 1520 leak proof design completely isolates the process from the switch. There are no O-rings or seals, and the customer will never need to worry about the
process fluid entering the switch compartment.” Quality, service and delivery have formed the foundation of SOR service to the process industry since 1956. SOR offers a comprehensive line of
pressure, temperature, level and flow instrumentation for a wide variety of industries and applications. Reader Reply Card No 127 Canadian Flow Products Achieve Patent in China
Two new Chinese patents have been recently granted for Analytical Flow Products (Canada). One of these patents is for the new rotary valve concept with purging grooves design. The other one is for the tight shut off concept of our diaphragm base valves. See Chinese patent # CN 101163912 B and CN 101011346 B. Both valves series are already in production.
The DV series diaphragm valves popular in sample stream selection, have had their electrical version ready since January 2011. This eliminates the need to have actuating gas. Also in January 2011, a high temperature version of the pneumatic G.C. rotary valve actuator will be released. Can be use directly in an oven up to 300°C, eliminating the need for the traditional standoff.
Most of the products literatures are now available in Chinese. Three new distributors have been appointed; Hardee Sales for Louisiana, Mississippi, Alabama and Houston area, Can Flow Technology Inc for the Canadian Market and EIF Filtres for France Market. In other news, the analytical and sample stream selection valves are now available for the NeSSI™ platform, as per ANSI/ISA-76.00.02-2002 standard.

Radar Level Transmitters Now Available with WHG Overfill Protection Approval
Emerson Process Management announces that its Rosemount® 5300 Guided Wave Radar (GWR) and 5400 Non-Contacting
Radar level transmitters are now available with approvals to the German Federal Water Act (WHG) regulations for overfill protection. Companies in the oil & gas production, refining, petrochemical, chemical, power industries and water and waste, will now benefit from the superior performance of Rosemount radar technology, while ensuring compliance with WHG overfill and water protection requirements.
The transmitters successfully passed the third-party test by TÜV (Technische Überwachungsverein), the German testing authority
responsible for testing overfill protection equipment according to requirements of the German WHG regulations. Proven instrument accuracy and reliability are key factors in the overfill protection approval process and the Rosemount radar devices were required to pass the comprehensive test of 5000 overfill situations for each transmitter, over the whole temperature range.
The Rosemount 5300 and 5400 Series are high performance 2-wire radar transmitters for challenging level and interface measurements on liquids, slurries and solids. The products take advantage of the company’s 30 years of proven radar expertise and are designed to improve plant profitability through superior reliability, state-of-the-art safety features, effortless handling and unlimited connectivity.
In both the Rosemount 5300 and 5400 Series, the analogue output which provides a continuous level measurement, can also be used to trigger an overfill alarm. The analogue signal is read by the control system which activates an alarm when a predetermined level is exceeded. In addition, the transmitters have an alarm function that indicates if the device has failed.
Innovations such as Direct Switch Technology (DST) for GWR and Dual Port Technology for non-contacting radar, make the Rosemount 5300 and 5400 Series the most reliable radar transmitters available. DST enhances the capabilities of the GWR to handle disturbances, longer measuring range and lower dielectrics, even with the single probe design. The Dual Port Technology built into the 5400 Series, enables a stronger signal than other 2-wire radar transmitters, providing better measurement reliability.
The robust designs prevent leakage and ensure reliable performance even under extreme process conditions. Heavy-duty probes are available to meet the extreme temperatures and pressure challenges with multiple layers of protection and advanced echo logics for reliable overfill detection. The 2-wire technology means that installation is fast and inexpensive.
The user-friendly graphical interfaces with wizards, measure-and-learn functionality, suggestions for application specific configuration and PlantWeb™ functionality, ensures that the transmitter integrates easily into new or existing control systems. Together with maintenance-free operation and advanced diagnostics, the result is a quicker return on investment with overall improved uptime and enhanced safety.
