Circular gear flow meters adopt positive displacement principle, delivering ultra-precise ±0.5% accuracy for low-viscosity & viscous low-flow liquids. With an ultra-wide 100:1 turndown ratio and tiny DN2–DN40 compact sizes, they support pulse, 4-20mA and RS485 Modbus outputs. Suitable for oil, resin, ink and refrigerant dosing in fine chemical, food and hydraulic industries.
Adopting high-precision circular gear positive displacement structure, this meter achieves up to ±0.5% high volumetric accuracy. Tightly matched gear clearance reduces fluid leakage, maintaining consistent measurement performance at ultra-low flow rates for high-standard dosing and precise fluid batching scenarios.
Gears are optional stainless steel, PEEK and ceramic materials with outstanding wear resistance. Hardened structural components minimize abrasion after long continuous operation, ensuring stable K-factor and excellent repeatability without regular calibration, cutting errors in repeated liquid proportioning work.
High-resolution magnetic induction sensors detect every gear rotation pulse accurately, with strong anti-electromagnetic interference capability. It delivers uniform, undistorted flow signals under variable working conditions, supporting reliable repeat measurement of tiny viscous fluids such as glue, lubricating oil and pharmaceutical reagents.
