Combustible gases start burning or explode upon ignition if the right concentration is present in air or oxygen. On the one hand there has to be enough oxygen on the other hand there must be a combustible material (e. g. combustible gases like propane, methane, hydrogen, natural gas etc.). The risk of a fire increases if the concentration of combustible gas increases. In case of a too high concentration of a combustible gas (upper explosion limit) the probability of a combustion decreases. Please pay specific attention to leaking containers or pipelines for escaping gases.
VA 550 and VA 570 flow sensors with ATEX approval ATEX II 2 G Ex db IIC T4 Gb (gas) resp. ATEX II 2 D Ex tb IIIC T90 °C Db (dust) can monitor the consumption and flow of explosive and combustible gases.
Our extra robust flow meter is available as ATEX-version for application in explosive areas
The measuring sections are available in flanged version or with R resp. NPT thread.
