ii UK Focus - Gas Detection


WWEM 2012 to Feature Gas Detection Zone


New Gas Detector Tube System


Air quality monitoring specialists, Enviro Technology (UK), have moved into the portable gas detection equipment market for the first time with the launch of the Kitagawa Gas Detector Tube System.


The Kitagawa Gas Detector Tube System is a complete sampling and analysis system for detecting hazardous gases and vapours on the spot and is used by industries worldwide to protect personnel, residents and help safeguard the environment.


The system consists of a pump and glass detector tubes filled with an absorbent material and chemical reagent which, in the presence of the target gas, produces a coloured stain along the tube. A calibration scale is printed on the tube to enable the user to easily match the length of the colour stain to the concentration of the gas present.


The organisers of WWEM 2012, the Water Wastewater & Environmental Monitoring event (Telford, 7/8th November 2012), have announced that this year’s show will again feature a Gas Detection Zone following the popularity of this section at the last WWEM in 2010.


The Council of Gas Detection and Environmental Monitoring (CoGDEM) is helping to organise the gas detection zone which will focus on new technology and products to detect hazards such as exposure to low oxygen levels in confined spaces and to toxic and flammable gases in the workplace. CoGDEM’s Leigh Greenham says “This year there will be more stands featuring gas detection technology as well as hazardous area (Ex) products, in addition to a wider range of free workshops covering topics such as ‘bump-testing versus calibration’, ‘confined space entry’, ‘VOC detection’ and much more.”


New gas detection techniques will be on show and the new ‘CoGDEM Guide to Gas Detection’ hardback book will be launched at the event. Many of the world's leading gas detection experts' products and services will be on display at the WWEM 2012 exhibition, including Air Products, BOC/Linde, Crowcon, Draeger, GMI, GfG, ISC, Infratec, Scientific & Technical Gases and Sira.


WWEM organiser Marcus Pattison is delighted with CoGDEM’s participation. He says: “With so much taking place during the two days, WWEM 2012 will be a hive of frenetic activity, but with free entry, free parking and free lunches and refreshments for pre- registered visitors, we have tried to remove as much of the stress, hassle and cost associated with other events.”

Infrared Gas Detector for Halocarbon Refrigerants


The fixed infrared gas detector for halocarbon refrigerants manufactured by Murco (Ireland) now offers an alternative to aspirated IR systems. Our new infrared detector has been specifically designed to offer better performance at a fraction of the cost of many competing products. It is suitable for supermarket and industrial applications and can detect most popular refrigerant gases.


The halocarbon IR gas detector is a new addition to Murco’s MGS gas detector range and offers reliable, real-time and continuous monitoring of potential hazardous leaks. This eliminates the problems that may occur with aspirated systems due to blocked filters, damaged tubes and delayed air sample analysis. The popular MGS product is a 12/24 volt gas detector with analogue and relay outputs. It can be installed on a standalone basis or integrated into a controls or a building management system.


Murco has built a reputation for being a leading manufacturer of fixed gas detection sensors. This new infrared detector for halocarbon refrigerants offers a lower cost high performance alternative to aspirated systems and is a welcomed addition to Murco’s fixed gas detector product line.

Enviro Technology’s Sales and Marketing Director Duncan Mounsor said: “In gas detection, portability and fast response are essential. Measurements must often be taken in difficult conditions, such as up ladders, in shafts or in areas where breathing protection is required. The Kitagawa system is easy to operate with a single pump action, providing a direct reading of the gas concentration, enabling fast and reliable measurements in locations that are difficult to access.


“Extra apparatus available for the pump provides users with access to remote testing in confined spaces and, as no electricity is required to operate the system, there is no added risk of explosion.


“With over 300 Kitagawa gas detector tubes available, we can arm organisations with the ability to measure every gas under the sun from Ammonia to Xylene.”


Ideal for use as personal detectors or as monitors for post-event surveying, the Kitagawa system is designed for single-handed operation, even while wearing gloves and is straightforward to use.


Later this year, Enviro Technology will be launching an on-line ordering system later for the Kitagawa Gas Detection Tube System and the gas detector tubes.

Approved Gas Detector Calibration Service


Castle Group (UK) has become approved to offer calibration on BW (by Honeywell) gas detectors. The company has added this to the ever broadening range of equipment it can offer for calibration and can provide the service to a broad range of BW instruments.


Simon Bull, Managing Director of Castle Group said, “This is a great development for Castle. We have been expanding our calibration offer for some time now and have been able to carry out calibrations on gas detectors of most makes. It is great to be in a position to put focus onto the BW range and it backs up our commitment to the selling of those products. I’m sure our customers will be pleased that we can now offer the full service.”


Castle’s range of calibration includes equipment for measuring Noise, Vibration, Temperature, Air Velocity, Humidity and light, among others and has grown considerably from humble beginnings when the company only ever dealt with sound measuring equipment.


The service manager for the company, Michael Mann stated, “It’s been an interesting journey and there’s plenty more to do but we are very pleased with the way we have been able to integrate the calibration of gas detection equipment into our procedures without too much difficulty. The training provided by BW was excellent and has given us the confidence to offer this to customers in the knowledge that we can do a good job.

Analysers and Flow Meters Help Maximise the Biogas Process


With increasing volumes of UK waste now being processed to create biogas from AD (Anaerobic Digestion), Bio-gas plant operators need to ensure that working capacities are maintained and optimised whilst risks are minimised. From small agricultural sites to larger industrial AD plants, accurate and dependable online gas composition analysis and flow rate measurements are essential to maintaining safe and profitable Anaerobic Digestion operations.


To meet this need, Allison Engineering (UK), who are specialists in control, instrumentation, gas detection and analysis, has introduced a range of Biogas analysers and ATEX certified flowmeters. The range of analysers includes the Awi-Eco, a low cost, compact discontinuous


analyser which provides 50 CH4 and CO2 measurements per day, with 4-20mA output and USB connection.


For more sophisticated monitoring and analysis requirements the Awi-Flex provides continuous measurement for CH4, CO2, H2S, O2 and H2. This system provides up to 5 measuring points; Ethernet, Profibus, Modbus and USB connection. Most importantly, it can


also be used to take flow, temperature and pressure inputs and undertake automated desulphurisation control.


All Awite analysers utilise a rugged, touch screen industrial interface which allows easy access to recorded data, sensor parameters and system diagnostics. This ensures that all information is instantly available, remotely.


Measurement of dirty, saturated gas at low flow / low pressures makes Biogas a difficult application, so the need for effective and reliable measurement is important. For these applications, Allison Engineering offers it range of FCI ST ATEX certified ‘no-moving’ parts flowmeters which utilise thermal dispersion technology, so they are particularly suited to the challenges of Biogas applications. Ease of installation, negligible pressure drop and mass flow output has proved the ST51 to be an ideal alternative to conventional DP cells and turbine meters. In addition, the sensor can be removed ‘live’ with the optional 1” BSP ball valve.
