• Proven Dual isolation (DBB) of the process from the environment during orifice plate changes
  – no need to isolate the complete metering  stream
• Minimized venting of gas volume
  – only the small volume contained within the meter upper chamber is vented
• Substantial saving in operating costs and production
  – potential annual savings of $50k per stream in reduced downtime
  – typically only 30 minutes to exchange a plate instead of many hours
• Elimination  of parallel streams or bypass lines
  – less maintenance and less inspection time
  – reduced weight and cost
  – a higher level of visible safety
