The Oval Gear Flow Meter is a positive displacement flow meter designed for accurate volumetric measurement of high-viscosity liquids. Inside the meter, two precisely machined oval rotors rotate as fluid passes through, transferring a fixed volume with each revolution. This makes measurement independent of flow profile and turbulence, ensuring consistent accuracy.
It is particularly suitable for heavy oil, resin, polyvinyl alcohol (PVA), adhesives, and other thick fluids, and can achieve precise measurement even at very low flow rates. The meter supports multiple signal outputs and is widely used in process control and custody transfer applications.
Precision:
Typical accuracy ±0.3% to ±0.5% of readingVersatility:
Works with high-viscosity and non-conductive liquidsDurability:
Hardened materials for wear resistanceLow maintenance:
No straight pipe requirementsEnergy savings:
Low pressure drop reduces pumping costs
Heavy oil, bitumen, lubricants
Resins, adhesives, polymer solutions, PVA
Syrups, edible oils, molasses
Solvents, varnishes, inks
Precise low-flow dosing and blending
