New Detector Allows Methane Leaks from Landfills to be Quickly Identified and Localised

Crowcon’s (UK) new Gas-Tec portable gas detector is designed to rapidly identify and localise methane leaks from landfill sites and waste processing facilities. Using Crowcon’s tried and tested flame ionisation chamber, the Gas-Tec also features next generation technology such as GPS, data and event logging. The new device allows survey teams to track progress and quickly pinpoint and record areas of significant interest.

Methane poses a severe explosion risk, is damaging to surrounding plant life and is also a greenhouse gas. It is generated during the working life of a landfill site and for as long as 30-40 years after a site has been covered over. The UK Landfill Regulations (England and Wales) 2002 stipulate that all landfill site operators carry out effective monitoring of this and other gases for a set period after closing, as stipulated by the Environment Agency.

Storing survey reports and service and calibration records are also a more frequent requirement, influenced by health and safety regulations. Finally, with many operating companies being forced to reduce personnel, there is an increased demand for products that require minimal training and set-up times to use.

Crowcon developed the Gas-Tec specifically to address these issues, including features to help companies identify methane leaks quickly and efficiently, with minimal manpower. GPS position logging, for example, enhances record keeping by assigning latitude, longitude and distance above sea level to data readings. Users can also view their current location, offering the precise location to back-up crews for immediate leak management. Another useful feature is data and event logging, allowing users to download full survey information for survey traceability using ‘drag and drop’ via a USB interface.
