66 Gas Detection 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.
The INSPECTRA® Laser portable detector developed by GAZOMAT™ (France), is used for on-foot inspections. The equipment, which benefits from high performance laser spectroscopy technology, offers below 1 ppm sensitivity as well as total selectivity to methane.
Eager to meet gas companies’ traceability requirements, GAZOMAT™ introduces a new survey software. The NGS software has been designed to ensure total traceability of network monitoring, both from vehicles and on-foot. In addition, GAZOMAT™ now offers a unique product pack that combines the powerful measurement system of the INSPECTRA® capabilities of the NGS software and the convenience of the GPS tablet system.
Laser with the
The GPS tablet displays the map of the survey mission on screen. The NGS software loaded onto the GPS tablet interfaces with and controls the measurement equipment to provide: Real-time visualization on the downloaded road map of the operator’s position and the survey mission’s progress, plus any gas concentration detected; 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; 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; and 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. The whole set offers gas companies a powerful measurement and positioning tool characterised by its user-friendliness and its traceability.

Ion Science introduces GasClam, the first gas monitor to give continuous, unmanned ground-gas data collection. Its ability to log long-term, real trend information is a revolution in gas management and risk prediction allowing informed decisions to be made on accurate, reliable data. GasClam measures methane, carbon dioxide
and oxygen concentrations as well as atmospheric pressure and temperature. Optional CO, H2S and VOC, plus water depth are with a telemetry module for remote, real time data communication. Sampling frequency can be set and is variable from two minutes, to once daily. Data is downloaded to a PC or viewed remotely using the optional GPRS telemetry system.
Manufactured from stainless steel, GasClam is Intrinsically Safe, environmentally sealed and ingress protection rated IP-68. Battery operated, GasClam can be powered for up to three months based on hourly sampling. Target applications include landfill for long term profiling, brownfield for development issues, monitoring for coal mine fires, leakage in crude/petroleum, solvent storage and filling stations, refineries for local compliance, and for below ground carbon capture and storage monitoring
regimes.Visit the new Ion Science website for more information:

Reader Reply Card no 209 New PID Sensor Released
With a PID (Photo Ionisation Detector) the sample gas is exposed to deep ultraviolet light from a lamp. The emitted light ionises targeted gases in the sample so they can be detected by the gas detector and reported as a concentration (ppb or ppm).
The Alphasense PID can be installed in portable and stationary gas monitors that accept either Alphasense Ltd CH-A3 or other manufactures compatible pellistor cells.
Thus providing complete PID capability in a package that has the same dimensional and electrical profile as Pellistors (providing the electronics input circuit is designed to take the sensor’s output range). This opens up an incredible variety of environmental and safety applications in industrial, commercial and residential markets.
The Alphasense PID sensor is offered in two models. They are virtually insensitive to humidity changes, providing unparalleled performance in a variety of applications: PID-A1 has a linear dynamic range of 50-ppb to 6,000-ppm (Isobutylene), PID-AH has a linear dynamic range of 5-ppb to 100-ppm (Isobutylene), the Sensors include a Detector with 10.6eV Lamp, Lamp Driver, Amplifier Circuitry and Removable and Replaceable Electrode Stack & Particulate Filter.
Arthur W. Burnley – Sales and Marketing Director stated: “Alphasense commitment is always to provide the best product it can in the market for its customers. We constantly improve, develop and introduce new products and the recently released PID range is an excellent example of this. Our policy is to introduce ‘best by design’ sensors, not ‘me too’ products.

These PID sensors have already been fully tested and adopted by a number of OEM’s and are beginning to replace our competitors products. A major benefit is the much lower cost for replacement lamps and the ability to replace the electrode stack at a nominal cost.
Alphasense maintains its commitment to customers by continuing to supply the highest quality sensors with on-time delivery every time allied to exemplary support.”

New Intelligent NDIR Sensor for CO2 or HC Detection
IRNET is the base of the new family of infrared sensors developed by N.E.T. (Italy). Using a patented optical cavity combined with latest NDIR technology the result is a high performing, robust sensor for Hydrocarbon and Carbon Dioxide monitoring with an estimated lifetime of over 5 years. The wide operating temperature (-40°C to 50°C) and low power consumption makes it suitable for fixed gas detection instruments. It is designed to fit most instrument makers in the standard 20mm and 32mm diameter sizes.
IRNET is available in two versions: the "dummy" 7 pins version, IRNET- 7, that provides a "raw" signal (active - reference) and an internal temperature signal or the “intelligent” version, IRNET-P, with incorporated signal linearisation and temperature compensation, suited for manufacturers without any specialist knowledge in IR technology. The IRNETP sensor contains all the necessary optics and integrated electronics that you need in order to provide a user-friendly analogue (voltage or dynamic pellistor) standard output. Both IRNET-7 and IRNET-P are available for hydrocarbon detection, including methane, in % LEL and % volume and for CO2 with detection level in ppm, low % volume and high % vol.
