Precision flow measurement drives efficiency in industries managing over $3 trillion in liquid products annually. Turbine meters deliver accuracy where it matters most.
Turbine flow meters measure liquid flow rates by counting rotations of a freely spinning rotor, converting mechanical motion into electrical pulses (typically 1-10,000 Hz). Their ±0.5% accuracy and 20:1 turndown make them ideal for petroleum (55% of applications), chemical (25%), and food processing (15%) where clean, low-viscosity liquids require precise measurement.
