AccuFlo - Model HMP -Certified High Accuracy Mass Flow Meter

• Accurate and traceable measurements outside of the jurisdiction of the measurement instrument directive are required (e.g. steam measurements),
• Very high measurement accuracy is required ,
• Very short straight pipe runs are available,
• A „Plug-and-Play“ solution is preferred,
• Reliable measurement results are required even under harsh operating conditions,
• The measurement needs to be insensitive against pipe vibrations,
