K-TEK's New Guided Wave Radar Level Transmitters Feature All-Digital Design and Integrated Graphic Display with Waveform ScreensMT5000 Series delivers speed and accuracy regardless of fluctuations in specific gravity or build-up on probesChicago, IL (October 25, 2005)- K-TEK, a leading manufacturer of state-of-the-art instrumentation for liquid level measurement now celebrating 30 years of manufacturing excellence, today announced at ISA 2005 the new MT5000 Series of Guided Wave Radar Level Transmitters. Designed for use in a variety of harsh environments, such as oil & gas processing and power generation, the series includes the MT5000 Liquid Level Transmitter and the MT5100 Level and Interface Transmitter. Both devices feature an integrated graphic display for quick and easy viewing of waveform screens. 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 due to temperature or pressure changes, and accurate level measurements are provided even with widely varying temperatures and pressures: up to 5000 psi (344 bar) or 800šF (427šC). The MT5100 also features a patent-pending interface weak signal detector that is able to detect the possible presence of a rag layer before emulsions can become a problem.All Digital Design with Integrated Waveform DisplayThe MT5000 Series features an all-digital design that delivers speed and accuracy in a compact unit. Built-in linearization functions allow users to minimize the unmeasurable or "dead" zones that can occur at the end of probes. While competitive products assume standard dead zones, all MT5000 Series devices incorporate a linearization table that can also be used for tank strapping.The MT5000 Series includes an integrated graphic display with waveform screens that detail signal activity. Configuration and commissioning are quick with easy-to-follow setup menus. Multiple menu languages are supported- English, French, Spanish, Portuguese, Italian, Russian, and Mandarin - for deployment around the globe. The waveform screens can be used for fine-tuning transmitter operation or for troubleshooting.Unaffected by Changes in Specific GravityWith displacers or DP transmitters, measurement is dependent on specific gravity, which varies with temperature and pressure. This results in varying accuracies. By design, the Guided Wave Radar of the MT5000 Series measures level independent of specific gravity and therefore is unaffected by temperature or pressure changes. A wide selection of waveguide coupler and probe options allows the MT5000 series transmitters to measure level even in the presence of saturated steam, and in high temperature or high pressure hydrocarbon applications."Unlike open air radar devices that must grapple with beam divergence and echo problems, the radar signal of the MT5000 Series travels along a waveguide," said Robert Hotard, Product Manager for Radar and RF products at K-TEK Corp. "This eliminates false echoes and minimizes signal loss. Being unaffected by variations in specific gravity, temperature, or pressure, the MT5000 Series is ideal for use in a wide variety of applications, including flare knock out drums in refineries and feed water heaters in power generation plants."Liquid Level & Challenging Interface ApplicationsThe MT5000 Series Guided Wave Radar Transmitters are available in multipleconfigurations: the MT5000 and the MT5100. The MT5100 provides the same robust features as the MT5000, but is specifically created for interface measurement. The device needs only one probe mounted in a displacer chamber or stilling well to measure fluid interface, reducing buildup problems, simplifying installation and setup, reducing costs, and minimizing maintenance. Using guided wave radar, the device can measure both the top surface (upper level) and interface level in tanks containing multiple fluids, such as oil and water.The MT5100 is the also the only Guided Wave Radar Transmitter that is able to detect the possible presence of a rag layer. Employing a patent-pending interface weak signal detector, the device is able to determine the signal strength coming from the interface, compensate for a weak signal return, and provide a visual indication of the possible presence of an emulsion layer.Multiple Data Transmission OptionsThe MT5000 Series features a 2-wire, loop-power design with 4-20mA output.The device can also be equipped with HART or Foundation Fieldbus communications. The newest data transmission option, support for the MODBUS protocol, features a 4-wire, half-duplex configuration with FM approval pending. Largest Selection of Wetted Materials & Robust DesignAble to work under even the most extreme conditions, the MT5000 Series level transmitters provide the industry's widest selection of probe materials, including 316 Stainless Steel, Hastelloy C-276, Hastelloy B3, Monel, and Titanium. The standard housing is powder-coated aluminum with an optional stainless steel housing to handle corrosive environments. A dual-compartment design allows users to isolate the wiring and terminations from the sensing elements and internal electronics. The MT5000 is FM Approved for use in hazardous areas in its 2-wire, 4-20mA, HART configuration.Pricing & Delivery K-TEK's MT5000 Series Guided Wave Radar Level Transmitters are available for immediate shipment. Prices start at $1600. Delivery is five weeks from receipt of order.About K-TEK K-TEK is a leading manufacturer of state-of-the-art level measurement instrumentation for liquid detection.
