New Network Survey Software Offers Traceability and User-Friendliness
New safety legislation in Europe requires gas distribution companies to monitor their networks on a regular basis (once, twice or three times a year depending on the country). As a result, they are under an increasing obligation to guarantee traceability of their surveys by providing precise location and dating of gas concentrations measured.
Systematic leak detection is therefore part of the overall safety policy of gas distribution companies vis-à-vis the community and their own
workforce. Aimed at the early identification of any deterioration of the network, systematic leak detection enables timely remedial action. But network surveys are also part of any maintenance policy, with the dual aim of increased safety and operating efficiency.
Gazomat™ S.A.R.L. (France), a company of T.D. Williamson, Inc. (France) manufactures a whole range of equipments used for network inspections both from vehicle and on-foot. The devices integrate the proprietary Inspectra® selectivity to methane.
Laser system that offers 1 ppm sensitivity and a total
Eager to meet gas companies’ traceability requirements, Gazomat™ introduces a new survey software. Designed to ensure total traceability of network monitoring, both from vehicles and on-foot, the NGS software controls the whole measurement system and provides :
This software offers real-time visualisation on the downloaded road map of the operator’s position and the survey mission’s progress, plus any gas concentration detected. In addition; users will enjoy the permanent saving of key survey data, such as concentrations measured, associated GPS coordinates, precise address on the map and operator comments. An interactive and simplified interface with the operator, including pop-up windows and easy-to-understand graphics to guide the operator throughout the mission is also part of this software package. A GPS type mapping system – the software integrates a GPS type map, which gas companies can supplement further with building or pipeline network maps in SHAPE format, a standard format used worldwide is also included.
• A final survey report in PDF format compiling the information on the survey mission, as well as all events recorded during the mission plus functional tests of the measurement equipment. Reader Reply Card No 100 Years of Experience Creates the Latest in IR Sensor Technology
For more than 100 years, Oldham from Industrial Scientific has specialised in safety and more particularly in gas and fire detection. The company offers a wide range of single gas and multi-gas portable detectors, fixed transmitters and controllers. Their products are always application-driven and solution-oriented. Whether for a single application or multiple rooms and areas, our monitoring solutions have been developed to meet the unique needs of our customers.
Oldham’s Research and Development department designs equipment that meets the latest international standards. They are dedicated to developing gas sensors, detectors and control units that meet or exceed these requirements.
The company’s latest fixed monitoring solution combines the OLCT100, OLCT80 and OLCT60 gas detectors with the XP IR infrared sensor. This completes the Oldham line of fixed systems.
This new patented IR sensor from Oldham makes the OLCT100 XP IR one of the best and most reliable infrared detectors on the market. Infrared detection technology offers significant advantages when compared to catalytic detectors:
This sensor offers fail safe technology: optical detectors continuously control the intensity of infrared light sources. This intensity is maximal in the absence of gas, so any decrease in intensity will indicate that gas is present! XP IR requires far less maintenance than competing sensors, it is also immune to poisons, has a very long life expectancy and can operate in oxygen deficient atmospheres.
The OLCT100 XP IR was also developed to conform to the safety standards IEC 61508 and EN 50402. This means that the complete component design process has been analysed, verified and validated (including specifications definition, design methods, design tools, testing methods, review techniques and documentation).
As a result, the OLCT100 XP IR is SIL 2 certified according to IEC 61508 / to EN 50402 (EN 50502 is an European derivative standard from the generic IEC 61508: Electrical apparatus for the detection and measurement of combustible or toxic gases or vapours or of oxygen – Requirements on the functional safety of fixed gas detection systems). And, its Probability of Failure on Demand (PFD) is 0.35 10-3 with a yearly interval maintenance test.
With a century of expertise behind them, Oldham offers a wide variety of other helpful support services. Their highly professional, yet friendly, staff are always on hand to answer whatever technical questions you may have.
Reader Reply Card No 124 Chlorine Gas: Danger and Detection
Properly installed, reliable gas detection can help prevent chlorine-related injury or death. In the workplace where chlorine is part of the process, fixed gas detection is the first line of defense for early warning of chlorine leaks and for changes to specific processes to stem and stop the leak.
Detector Electronics’ (USA) GT3000 chlorine gas detector’s electrochemical cell has a range of 0-10ppm and performance verified to FM6340. The GT3000 can be installed as a stand-alone device with 4-20mA output with
HART protocol, local LED indicators, and magnetic calibration. Or the sensor/transmitter can be combined with a local or remote display, such as the Det-Tronics’ FlexVu Universal Display.
Detector Electronics offer a new application note which illustrates considerations for detecting chlorine gas in a wide variety of applications.
