Gas Detection 5
The EASY INSPECTRA™ equipment that can be installed in small-size carriers revolutionizes the very concept of network survey by combining both pedestrian and vehicular detection..

If the measured concentration exceeds a given limit, the operator can immediately verify it on foot using the portable INSPECTRA®
LASER
detector with a sampling rod ending in a suction cup that is set directly on the ground, and then resume survey from the vehicle. The other option is that the vehicle completes its journey and all the indices detected are then verifi ed on foot using a portable INSPECTRA®
LASER using the
geolocated data as provided by the vehicle survey.
The combination of a short response time, total methane selectivity and ppm-level sensitivity guarantee the precision and accuracy of measurements and leak detection.
The NGS software combined with a high-reception quality GPS antenna (dead reckoning) continually positions the vehicle (compensating for the tunnel effect), even when satellite reception is poor due to buildings, underground car parks, etc.. The software links the indices detected and the GPS position in real time for accurate geolocation, making it easier to subsequently look for the leaks in the fi eld.
The software operates with GPS type background maps of the country, which can be supplemented with information specifi c to each gas operator (system maps, pressure regulator stations, land registry maps, etc.) generated in a Shape format - a standard map format.
During an assignment, the software shows the position of the vehicle in real time along with the detected leak indices, maps and all the information loaded at the start (system map, distribution map, roads, buildings, etc.).
A summary report in PDF format is automatically issued at the end of each survey mission with screen shot for each gas leak detected to facilitate its location later on.
The automatic logging of key survey data (measured concentrations, malfunctioning, annotations, measuring system tests, etc.) with their location in longitude and latitude and the precise date provides a detailed image of a section of the network at a given time.
At the end of the survey, a summary report is generated in PDF format that brings together all the events that have occurred, with, for each detected index, a separate detailed record with a screen shot for future location.
The simple graphics interface and the operating procedures make the work of operators easier and reduce the time for training use of the new technology, however advanced. The high usability of the software, which only displays vital data and guides the operator during the mission, even offers gas companies who wish to do so the facility of reducing the crew to just one operator/ driver, while complying with road safety rules.
The INSPECTRA’s detection system adapts easily to all carriers, including those with a slight build, with the same performance. This recent innovation has made it possible to effectively combine detection on foot and from a vehicle for higher productivity and maximum effi ciency in city centres and areas that are diffi cult to reach.

INSPECTRA system adapts easily to all carriers
Latest advances in mobile communication systems and devices open up exciting new perspectives for gas leak monitoring. These are already changing the way fi eld survey data may be collected, transferred and shared within the maintenance crews for immediate and focused action.
Mobile application for easy survey data transfer
The mobile application module recently developed by GAZOMAT, complementing the NGS software, aims to provide gas utilities with a fully interconnected and integrated monitoring system ensuring fi eld data integrity as well as survey teams’ time optimization. With such tools, gas operators will even be able to remotely follow, in real-time, surveys in progress.
A dynamic 3D view of the journey completed is possible with Google Earth. It highlights in red the gas leaks detected that exceed the critical concentration level threshold.
The EASY INSPECTRA™ mounted on an ATV makes it possible to survey gas transmission pipelines or off-road areas.
These recent innovations have been developed to offer a number of dynamic solutions that can be deployed by gas operators on an “à la carte” basis to tailor the management of their systems to their needs.
