Gasmet Technologies (Finland) have announced that their FTIR-based Continuous Emissions Monitoring System (CEMS) has received approval from TÜV, the international certification body, for the EN 15267-3 standard, which is more recent and more stringent than the existing German Type Approval and QAL1 certificate, EN14181. This means that the Gasmet CEMS is approved for additional calibration ranges and an increased H2O range up to 40%.
Highlighting the importance of this certificate, Gasmet’s Antti Heikkilä says “The ranges for CO, NO, SO2, H2O have been increased and this certificate demonstrates the low, fully compliant, measurement uncertainties that we can achieve. This is a good indicator of the high quality of the analyser, but it also offers practical advantages. For example, the low measurement uncertainties for N2O and CO2 (5% of measuring range or less) mean that the CEMS system can now be used to monitor Greenhouse gases for emissions trading in addition to measuring pollutants for compliance monitoring purposes.”
Specific controllers and analysers are installed to perform a continuous emission monitoring (CEM) of chimney emissions, to detect the release of dangerous gases, or to analyse ambient air quality.
Detcon’s (USA) rugged new CXT-Series wireless gas detection sensors are designed for use in heavy industrial environments and especially suitable for mobile applications. These “environmentally bulletproof” field devices include fully encapsulated sensor electronics housed in a stainless steel enclosure, thereby eliminating potential damage that may be caused from water ingress.
At the Liulitun landfill in Haidian District of Beijing, the operator specified their requirement for a landfill gas analyser with ‘high accuracy and strong stability’. After a competitive pitch by Geotech distributor, Onuee Electronics, they selected the Geotech (UK) GA3000 fixed landfill gas analyser.
OTT Hydrometry (UK) will unveil a new groundwater monitor, a new portable flow meter and a new range of dataloggers at WWEM 2012. OTT MD Simon Wills says “This will be a very exciting event because we will be launching new technologies in almost every area of hydrometeorology.”
