A New Addition to the Portfolio of Metallurgy Fairs: Valve World Expo to Premiere End of 2010 in Düsseldorf
A new and highly promising trade fair has joined the ranks of international metallurgy fairs hosted by Messe Düsseldorf. From 30 November to 2 December 2010, the international trade fair Valve World Conference & Exhibition will premiere in the Düsseldorf exhibition halls, accompanied by a congress for industrial valves. Valve World opened its gates in 1998 and took place bi-annually in Maastricht, The Netherlands, until it grew too large. In 2008, the Messe Düsseldorf GmbH (Germany) bought it as an internal event. An international marketing campaign, which was even nominated for the 2010 edition of the German Advertising Yearbook, advertised the move from the Maas to the Rhine.
The gates of fair halls three and four will open from 30th November onwards. More than 460 companies from 34 countries will display plants from the areas such as gaskets, sealing materials and tubular products for valves and services. Relevant associations and publishers will also be present. More than 13.000 net square metres have been reserved. Next to German companies, the majority of exhibitors come from Italy, Great Britain, The Netherlands, Taiwan, USA, South Korea, India and China. The accompanying Valve World Conference will take place in the Congress Centre South (CCD South), directly next to hall three. KCI, publishing from the Netherlands is responsible for the conference, which is expected to draw more than 500 participants.
Producers of components and end products will find their suppliers in the ranks of the exhibitors, whereas large makers of plants will find their components on display by other participants of the Valve World Expo. The organisers expect a total of around 7.000 professional visitors, coming from different sectors including the chemical and plant engineering industries. The three-day fair will take place from 9.30 am to 18.00 pm. A day ticket costs €25 and a season ticket for the event costs €40. A fair catalogue can be obtained for €10. Tickets can be ordered from the internet portal for a reduced price. Online prices are €19 for a day ticket and €35 euro for a season ticket. Up-to-date information can be found on the internet portal;

New Low Cost Level Transmitter
L&J Engineering (USA) recently announced its new, low-cost MCG 2420 Transmitter.
The MCG 2420’s versatile design allows it to be easily installed into existing applications. The MCG 2420 can easily couple to the Shand & Jurs Model 92302 & 92303 Liquid Level Indicators, and also the Varec 6700 Liquid Level Indicator.
The MCG 2420 boasts a number of key features present in its sister-transmitter, the MCG 2000MAX, including Absolute Magnetic Encoding. The MCG 2420 runs on ultra-low power and does not require batteries or eproms.
L&J has replaced the foot and inch optical discs with foot and inch magnets which provide much greater accuracy and reliability and also allows for the option of using a much smaller housing than previously possible. The MCG 2420 has an expanded range of 0-128 feet. By using absolute magnetic encoding the number of parts required is greatly reduced in turn providing unmatched reliability.
“The MCG 2420 shows L&J Engineering’s innovation in the level gauging market,” Product Manager Jim Jannotta said. “It’s designed to ensure maximum reliability in critical level gauging applications and has an optional LCD display so level can be recorded at the tank or transmitted back to the control room via wires or wirelessly.”
Similar to other L&J Engineering Transmitters, the MCG 2420 is completely unaffected by power failures in your tank farm without the use of batteries. When power is restored the transmitter will accurately reflect the current level, even if it has changed, without the need for additional calibration.
Along with all other L&J level gauging equipment, the MCG 2420 can communicate with L&J Engineering’s MCG 3630 Touch Panel Tank Monitor.

Versatile LM80 Laser Level & Positioning Transmitter For Dry Bulk and Liquid Level Applications
K-Tek (USA), today announced the ATEX approved LM80 laser transmitter for non-contact level measurement and positioning. Designed for a variety of applications, the LM80 measures positions over very long ranges; up to 500 feet (150 meters). The device also accurately measures level at distances up to 100 feet (30 meters). Whether handling plastics, coal, grain, or aggregates, the LM80 can measure any solid surface at any angle.
The small wavelength of the laser means a narrower beam with virtually no beam divergence and, therefore, no false echoes. This provides high accuracy readings even when dealing with the most challenging circumstances, such as measuring into silo cones, even inside silo chutes and through narrow openings in protective grids. The LM80 can be installed on any existing silo nozzle, three inches or larger, regardless of location.
The LM80 features an all-digital design that provides speed and accuracy in a compact unit. An advanced timing system and self-correcting signal processing functions allow the device to accurately and reliably make measurements in the harshest conditions. The system can select the true signal even in the presence of dust, as is commonly found in silos of coal, plastics, or grain, as well as in underground mines or quarries.
The advanced signal processing software in the LM80 automatically compensates for colour differences in the materials being measured. The device is able to easily distinguish between dark colour surfaces such as coal, and light colour surfaces such as plastic pellets and aggregates. The unit can also measure the position of moving targets over long distances, such as overhead cranes and tripper cars. Thus, one unit can handle both long distance positioning and level measurement applications at one third the price of competitive models.
The LM80 includes last pulse detection, which selects true signals from among the many that are reflected from dust clouds, agitator blades, or other obstacles. Variable gain allows the device to select the best return signal in quickly changing visibility conditions, such as dust, vapours, and materials of different colours. A built- in filtering system allows the unit to handle rapid level tracking applications, such as rock crushers or aggregate process hoppers, as well as slow moving levels, such as in inventory silos. The laser transmitter is housed in a powder coated aluminium enclosure, IP66 rated. It is FM certified for Class I Div 2 Group A,B,C,D and ATEX for Ex nA nC II T4.
Dual internal compartments isolate the optical components from the wiring terminations, eliminating the possibility of moisture build-up and errant readings. Stainless steel dust tubes with built-in purge port prevent dust build-up and protect the optical lens from being coated. The LM80 is a compact, stand-alone unit that is quick to set up and install. It requires no calibration or special configuration. The unit is easily programmed with a compact handheld device. An optional laser pointer provides precise alignment. Portable mounting options allow users to position the laser in any direction.
Reader Reply Card No 45 43 The high-quality and user friendly features of the HPC400 make calibration tasks easy to
perform. All relevant information is shown on a large, multi-line graphical display. This includes 15 different pressure units, transmitter mA reading with 24 VDC supply onboard, min/max and peak recording, and semiautomatic pressure switch test. Opening and closing pressures are automatically recorded and deadband calculated.
The HPC400 can be delivered as an individual calibrator or as a complete calibration system ready for use in a carrying case, including pump, hose connectors, battery, test leads, user manual and traceable calibration certificate.
