ATEX & IECEx Zone 2 Hazardous Area Flow Meter

What is Hazardous Area Zone 2?

  • Zone 2 Hazardous Area – a potentially explosive atmosphere in which an explosive liquid or gas atmosphere is not likely to occur in normal operation and if it occurs will exist only for a short time. “Short time” is not officially quantified according to IECEx or ATEX but commonly accepted by hazardous area industries as being prevalent for less than 10h/yr.
