ADVANTAGE

Product Structure & Features

Detachable Cartridge: Integrated helical turbine, bearings, and gear transmission mechanism for easy maintenance/replacement

Housing: Cast iron/ductile iron/stainless steel (optional) with strong corrosion resistance

Helical Turbine: Horizontal axial-flow design ensures low resistance at high flows and stable measurement

Core Advantages

Low Pressure Loss：Horizontal helical structure minimizes flow resistance, ideal for large-diameter pipelines

High Maintainability：Removable cartridge allows partial replacement without full meter exchange, reducing maintenance costs

Wide Turndown Ratio (50:1): Accurate measurement from minimal flows (Q₁) to maximum capacity (Q₄)

Extended Lifespan: Wear-resistant bearings ensure ≥10 years service life (under normal conditions)
