FLOWSIC900

LNG drives energy diversification and reduces emissions in the mobility and energy sector. Plant operators however still face technical, operational and commercial challenges during LNG transfer. FLOWSIC900 solves these challenges. It is the result of our many years of experience in natural gas measurement: A flow meter specially tailored to the needs of the LNG-industry. FLOWSIC900 offers the required custody transfer accuracy for volume flow measurement and meets highest standards. FLOWSIC900 and the proven products FLOWSIC600-XT and FLOWSIC100 Flare-XT significantly increase measurement performance and reliability in LNG plants - a complete solution portfolio from a single source.
