How does a dual-rotor flow meter work? What fluids is it suitable for?
Dual-rotor meters are PD type: meshing helical rotors displace fixed volumes, ±0.2%R~±0.5%R accuracy, ideal for diesel, HFO, lubricants and custody transfer.
A dual-rotor flow meter is a positive displacement (PD) meter. Two meshing helical rotors form sealed measuring chambers with the housing; fluid flow drives the rotors, and each revolution displaces a fixed volume, enabling precise totalization.
Key traits: high accuracy (±0.2%R~±0.5%R), insensitive to viscosity changes — ideal for diesel, heavy fuel oil, lubricants and chemical liquids, including custody transfer.
