Factory engineers often struggle finding flow measurement solutions for steam and aggressive gases. Vortex flow meters solve these challenges with their unique non-contact measurement principle.
Vortex flow meters optimally measure steam, gases, and low-viscosity liquids in 5 key applications: 1) Steam energy monitoring (80% of industrial use), 2) Compressed air systems, 3) Natural gas flow, 4) Chemical processes, and 5) HVAC refrigerant circuits. Their no-moving-part design ensures 10+ year lifespan in these demanding services.
