Menu item for the metrological quantification of methane emissions in accordance with DVGW G 425. Quantification is to be carried out, for example, on underground installations using the extraction method or on above-ground installations using bagging. Extraction can be carried out using the Esders Vakumobil or the internal pump of the Laser Hunter. Methane emissions are calculated in accordance with the EU Methane Regulation and DVGW G 425-2 / G 425-3. The measuring range and resolution in the menu item depend on the sensor hardware in the Laser Hunter.
