Measurement and Testing Portable Gas Chromatograph Launched
AMETEK Process Instruments (USA), a specialist in online analytical instrumentation with one of the industry’s most extensive product line, has introduced the Chandler Engineering Model 292B portable gas chromatograph for the determination of the energy content (BTU) of natural gas.
The AMETEK Model 292B natural gas chromatograph is designed as a truly portable analyser. The Model 292B BTU analyser features a fully integrated sample handling system, rugged gas chromatograph (GC) module, and enhanced data processing and handling capabilities, including a state-of-the-art LCD colour display and user interface.
Gas analysis starts with the touch of a button. Sample transport, signal integration and system diagnostics are handled within the unit to ensure accurate, reliable and repeatable analysis. The unit’s advanced electronics platform accurately determines energy content, relative density and compressibility based on industry- standard calculation methods.
Integrated optimisation functions result in exceptional sensitivity and peak performance. An integrated sample inlet manifold allows for single point connections of sample and drive (carrier) gases, permitting installation either as a stand-alone analyser or integrated into a mobile platform such as truck, van or other vehicle.
Sample results, including “live” chromatograms, raw data information, analysis reports and calibration data can be easily viewed on the front-panel LCD display. System and analysis reports can be retrieved via a USB port, customised to meet user requirements, and printed directly from the unit using an industry standard USB printer port connection.
The Model 292B’s advanced software and two onboard computers allow the unit to calculate heating value, relative density and compressibility using the AGA-8 method. The system also analyses composition with exceptional accuracy. Oven temperature is precisely controlled, eliminating errors caused by ambient temperature fluctuations.
In addition, the unit’s Thermal Conductivity Detectors (TCD) provide extremely high sensitivity, even for low concentrations of components. The instrument’s TCD bridge is balanced automatically before each analysis to ensure peak performance and repeatability.
AMETEK has manufactured laboratory and gas chromatographs for more than 30 years. Its proprietary manufacturing process ensures that the Model 292B will maintain superior repeatability over its entire service life. Its experience in GC valve design further assures reliable and trouble-free operation.

Differential Pressure Gauge Specifically for Clean Rooms
With their air2guide product range for air handling technology, WIKA (Germany) also offers measuring solutions for clean rooms. For positive and negative pressure control in this field, the model A2G-05 differential pressure gauge with a minimal insertion depth (42 mm) has been developed.
The compact measuring instrument covers pressure ranges from 0 … 50 Pa up to 0 … 12,500 Pa and, -25 … +25 Pa to -1,500 … +1,500 Pa. It is available in a nominal size of 110 mm. With its very low depth dimension, the A2G-05 is especially suitable for recessed installation in clean room walls and doors. Installation is quick and easy: A system using a bayonet fitting means users only need half the time they would with other models.

www.petro-online.com Simply Optimal: PulsFox PMG 10 Level Indicator
The new AFRISO PulsFox PMG 10 guided micropulse level indicators from Afriso-Euro-Index (Germany), have been designed to measure the level of high-viscosity or low-viscosity, adhesive, conductive or isolating liquids or bulk solids, for example in storage or process containers, silos or tanks.
The PulsFox PMG 10 level indicators,which operate on the basis of the guided micropulse principle, are available in the following versions: PulsFox PMG 10 MS with rigid mono probe, PulsFox PMG 10MF with flexible mono probe, PulsFox PMG 10 DF with flexible dual probe and PulsFox PMG 10 KX with coax probe. The user always has the optimum solution for their application at hand.
Regardless of high or low tanks, disturbing installations, small distances or conductive foam on the medium to be measured, there is a suitable probe for virtually any application. PulsFox PMG 10 feature san aluminium die cast housing and is suitable for rough ambient conditions. The measuring instrument has no moving parts and operates with high reliability and precision. The measuring accuracy is neither influenced by turbulent, steaming or dusty surfaces nor impaired by changes in density, pressure or temperature.
If required, the PMG measuring head can be equipped with a local display (programming display). The PMG 10 2-wire level(4-20 mA) indicator is fully maintenance-free and not subject to wear and tear. It is available with all standard process connections for use in hazardous areas (EX version). All versions of the PMG 10 series of level indicators are available for free download as 3D CAD models and since June 18, 2012 they can be directly integrated into system engineering.
